Description of the Invention (2) A long group of laser beams can be used to generate an integrated circuit of approximately 180nm. ArF fluoride excimer lasers are very similar to KrF lasers. The main difference is the wavelength of the laser gas mixture and the shorter output beam. Basically, argon replaces krypton and the wavelength of the output beam produced is 193 nm. This allows the size of the integrated circuit to be further reduced to about 120nm »F2 laser is considered to be the successor of KrF and ArF lasers in the integrated circuit photoengraving industry, because the 157nm beam allows pattern analysis above the main Improve. These F2 lasers can be very similar to KrF and ArF excimer lasers and can be slightly modified to operate as an F2 laser like KrF or ArF lasers of the prior art. A typical prior art KrF excimer laser used in integrated circuit production is shown in Figures 1 and 2. The sectional view of the laser chamber of the previous laser technology is shown in FIG. 3 "The pulse wave power system 2 powered by the high voltage power supply 3 supplies electrical pulses to the electrodes 6 placed in the capacitor chamber 8. A typical state-of-the-art photoengraving laser is operated at a pulse wave rate of about 1000 Hz with a pulse wave energy of about 10 mJ per pulse. Laser gas (for KrF lasers, approximately 0.1% fluorine, 1.3% tritium, and the rest is neon as a buffer gas) circulates between the electrodes at a speed of about 11,000 inches per second at about 3 atmospheres Space. This is done using a tangential blower 10 placed in a laser discharge capacitor chamber. The laser gas is cooled by using a heat exchanger 11 placed in a container and a cooling plate (not shown) installed outside the container. The natural frequency band width of the excimer laser is narrowed by the line narrowing module 18. Commercial excimer laser systems typically include many modules. They can be quickly replaced without disturbing the rest of the system.

Description of the invention (7) Efficiency; 4) The charging voltage of the pulse wave power system is more accurate Control: 5) A computer controller planned by the new algorithm program provides improved control of pulse energy and array energy and: 6) The electrode interval is reduced to 10mm. Chamber Modification Single Preionizer Tube As shown in Figure 6, a single larger preionizer tube 56A replaces the dual preionizer tube 56 shown in Figure 3. The single tube pre-ionizer is manufactured in accordance with the description of U.S. Patent No. 5,719,896 issued on February 17, 1998, which is incorporated herein by reference. Applicants have found that a set of pre-ionizer tubes is not only sufficient, but very surprisingly provides performance improvements over a dual pre-ionizer design. In the examples this pre-ionizer is placed upstream of the electrode. The applicant does not fully understand the reason for the improved performance. Applicants have learned that single tube pre-ionizers provide the stability of discharge and improve pulse-to-pulse stability. Referring next to Fig. 7, this pre-ionizer adopts an integrated tube design 'which has an insulating sleeve element 180 containing a reverse tracking groove 170 as an integral component of the tube. When the diameter of the rod portion 145 of the pre-ionizer and the OD of the insulating sleeve portion 180 are 1/2. The inner guide bar 146 has a diameter of 7/37 inches and the diameter of the connecting wire extending through the insulating sleeve portion and forming a ground connection is about 1/16 inch. The previous pre-ionizer tube design used a dual-diameter design with a rod section diameter of approximately 1/4 inch and an insulation sleeve diameter of approximately 1 inch. This makes it necessary to join the processing procedure to manufacture the insulating sleeve member. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210x297 mm) ------------------- -Order --------- Line / ^ (Please read the notes on the back before filling out this page) Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 412891 A7 ____B7_ V. Description of Invention (/ P) and Management Component combination. The design of thicker fixed-diameter tubes is the opposite of the conventional design rule, which predicts a reduction in ionization due to lower capacitance. In most designs, the thickness of the tube depends on the dielectric strength of the material selected. Those skilled in the art will understand the pre-ionizer tube design techniques used in the prior art to select materials with the highest dielectric strength and determine the wall thickness that matches this capacitance. For example, conventional sapphire materials have a dielectric strength from 1200 volts / mil to 1700 volts / mil. Therefore, if the laser is operated at 25kV, a 0.035 inch dielectric thickness provides a safety factor of 2. This design results in lower capacitance: but in laser operation, the practical effect of reducing capacitance is negligible, and there is a surprising increase in the measured geometrical radiation of the electrode gap. Because of the fixed diameter, thicker tube wall, and overall insulation sleeve design, a single piece of material can mechanically provide the counter-tracking groove 170. Due to the monolithic construction, there is no need to use ultra-pure (ie, 99.9%) polycrystalline semi-transparent aluminum oxide ceramic objects. • Although the applicant continues to use ultra-pure materials. The overall relationship between the insulating sleeve 180 and the tube 145 is artificially generated without the need to plan the surface of the difficult tube geometry for diffusion bonding. In fact, it has been found that the properties of high purity values are not as important as the porosity of the material . I have found that the greater the porosity | the more the dielectric strength is reduced. As a result, a commercial-grade ceramic object preferably has a purity of at least 99.8% and is low in porosity. For example, Coors Ceramics manufactured under the material NO.AD-99SF has a dielectric strength of 300 volts / mil. The product can be used. Insulating sleeve 180 with anti-tracking groove 170 configured therein, as previously explained, its function is to prevent the axial direction from the cathode to the ground plane 160 along the surface of the tube. 13 This paper size applies to China National Standard (CNS) A4 specifications.

Description of the invention (//) High voltage tracking. As explained above | The applicant has also found that a single preionizer works better than two sets of preionizers, and is better than the first A single pre-ionizer system is placed upstream of the electrodes as illustrated in the examples. The applicant has performed experiments using a single pre-ionizer placed downstream and found that at a certain blower speed, this configuration produces more than two sets of tube devices. The upstream configuration produces significantly better pulse wave energy stability. High-efficiency chamber printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). The chamber has been improved. The efficiency of the laser "single-piece cathode separator composed of aluminum A1203 Isolator 55A, which isolates the cathode from the upper chamber structure, as shown in Figure 6A. In the prior art design, eight separate sets of isolators were needed to avoid breakage of the isolators due to thermal expansion stress in the isolators. This An important improvement allows the head of the chamber to be made shorter, which significantly reduces the distance between the cathode 83 and the peak chirp capacitor 82. The respective capacitors 54A forming the peak chirp capacitor array 82 are moved horizontally closer than the prior art Cathode. In order to reduce the difference in thermal expansion between the monolithic isolator and the chamber structure, the upper chamber 8A is made of ASTM-A3C steel, which has a coefficient of thermal expansion closer to A 丨 203 than aluminum > chamber 8 The bottom part 8B is made of aluminum. But the applicant has found that the difference in thermal expansion between ASTM-A3C steel and aluminum is not a problem. Both the steel and aluminum parts are nickel-coated. For commercial photolithographic laser cathodes. The prior art is generally supported by the cathode support rod 53, as shown in Figure 3 "In this preferred embodiment, the cathode support rod is removed and the cathode 83 is formed slightly thicker and directly mounted on the unit. Slice Above the device 55A, "Cathode 83 uses 15 sets of feeds and passes 14 paper sizes. Applicable national standard (CNS) A4 specifications (210 x 297 mm)) 412821 Printed by A7 B7, Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs. The pole 83A and the connection nut 83B are connected to the high-voltage side 82A of the peak capacitor 82. In this preferred embodiment, the new anode support rod 84A is substantially larger than the prior art anode support rod and contains a gas stream The protruding piece 84B in the area »These two characteristics minimize the temperature change of the anode. The metal seal applicant has found that the elastic sealing material of the prior art reacts with the fluorine gas to generate pollution in the laser gas that reduces the laser performance. The preferred embodiment of the present invention uses a metal sealing material to seal the laser chamber. The relatively metal seal is a tin-plated Inconel 1718 sealing material. The Monel current return channel and the blade. The applicant also found stainless steel components. At the same time, it also reacts with fluorine and generates pollution in the laser gas. Therefore | In this preferred embodiment, the prior art stainless steel current return channel structure and gas flow blades are replaced with Monel alloy current return channels 250 and Monel alloy flow blades 252 and 254. The muffler applicant found that the main reason for the distortion of the quality of the laser beam produced by a narrow-band excimer laser operating at 2000 Hz or higher is the acoustic shock wave caused by the discharge of the pulse wave, which is reflected back from the structural component of the chamber To the space between the electrodes and to distort the laser beam of the pulse wave that occurs 0.5 milliseconds later "An embodiment described here (see Fig. 6A) uses an oblique arrangement provided on the two sides of the laser chamber Recessed silencers 63A and 64A minimize this effect significantly. These silencers absorb a portion of the sound energy and reflect a portion of the sound energy downwards into the area below the laser chamber.

Description of the invention) Keep away from the electrodes. In this preferred embodiment, the muffler includes a set of machine metal structures having a groove of 0.1 mil width > 0.3 mil depth and placed at intervals of 0.2 mil: a set of 0.3 mil depth recesses The grooves are shown at 63 of the silencers 60 in Fig. 6A. The actual test results show that these silencers significantly reduce the pulse quality distortion caused by sound shock waves. The applicant also found that the shock wave effect can be minimized by reducing its current during discharge. In fact, in the preferred embodiment of the invention, changes in the chamber head (discussed above) and new pre-ionizers designed to reduce acoustic shock waves without the need for a muffler. Fan Improvements The preferred embodiment of the present invention includes a major improvement in the prior art, gas circulator, which substantially improves laser performance. These improvements are in the construction of a copper-free blower blade structure—a new asymmetric blade configuration that significantly reduces resonance effects and improves its bearings. Silicon-free fan blade structure Applicants have found that a brass alloy welded material, which is commonly used in the construction of blower blades, is the main source of SiF6 in laser chambers. This gas significantly reduces the laser performance of the KrF laser and severely damages the ArF laser. The applicant found four solutions to this problem. First, the blade structure is machined into pieces from a solid block of material, in this case aluminum. Another solution is to cast the blade structure into segments. These segments are then combined with electron beams in a way that does not add new materials.

Description of the invention (/ hand) One method is to connect the blade to a frame structure using a solderless soldering process. Aluminum 6061 is used as the base material for all component fragments. These parts are then copper-plated before the soldering process. After all parts are combined, the fan is soldered in a vacuum furnace with low temperature solder, usually 91% tin (Sn) and 9% zinc (Zn). This solder was selected because it lacks silicon and has the ability to work with copper-plated aluminum. The assembled and welded fans are then nickel-plated. This manufacturing method results in inexpensive silicon-free fans. Reducing resonance effects Prior art hair dryer blade structures include a set of tangential hair dryers with 23 longitudinal blades. These blades are mounted symmetrically around the structure. The main resonance effect is measured according to the fan parameters and the actual laser performance. The disturbance in the laser beam shows its corresponding sound wave at 23 times the fan rotation frequency. The effect of unfavorable bearing performance was also measured corresponding to 23 times the fan rotation frequency. The improvement in the design of the fan structure is called an asymmetric blade configuration, as shown in Figure 14A. Another example of the fan blade structure shown in Figure 14B forms 16 separate milled or cast segments, each segment having 23 sets of blades to 360 relative to adjacent segments. / (15x23) · or about]. Rotating the segments • Another improvement in the grinding or casting method for the manufacture of the fan blade structure, which is relatively easy to form, is to form the blade into a gas tin foil, as shown in Figure 32 of the figure. The blades of the prior art are stamped and the cross-sectional views of the two sets of stamped blades are shown in comparison with 314 ° 3] 8 showing the direction of rotation and 320 represents the surroundings of the blade structure. Therefore, the conventional blade thickness is uniform, and the gas tin foil blade has 17 paper standards applicable to China National Standard (CNS) A4 specifications < 210 «297 mm): ------------- Order- ------- line (Please read the precautions on the back before filling this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 413891 A7 _____B7____ 5. Description of the invention (/ ^) Tear-shaped appearance, which includes circles Shaped leading edge, thick central portion and tapered trailing edge. Bearing Improvements Embodiments of the present invention will outperform the prior art with one of two bearing improvements. Ceramic Bearings-A preferred embodiment of the present invention includes ceramic bearings. Compared to ceramic bearings, silicon nitrides lubricated with synthetic lubricants, preferably peffluoropolya kylether (PFPE). Compared to prior art excimer laser fan bearings, these bearings generally provide longer life expectancy. In addition, neither bearings nor lubricants are significantly affected by the highly reactive fluorine gas. Magnetic bearings respond to other preferred embodiments of the present invention which have a magnetic bearing that supports a fan structure, as shown in FIG. In this embodiment, the shaft 130 supporting the fan blade structure 146 is then supported by a set of active magnetic bearing systems and driven by a set of brushless DC motors 130. The rotor 129 of the motor and the rotor 128 of at least two sets of bearings are sealed. Within the gas environment of the laser cavity and the motor stator 40 and the coil 126 of the magnetic bearing magnet are placed outside the gas environment. This preferred bearing design also includes a set of active magnetic thrust bearings 124, which also have a coil that is placed outside the gas environment. Gas powered anode support rod As shown in Figure 3, the prior art gas flow from the blower 10 is forced to flow between the electrodes 6A and 6B by the anode support rod 44.

Description of the invention (▲) Please find as shown in Figure 3 The support rod 44 designed by the prior art is shown to generate the main aerodynamic reaction force on the hair dryer, which is sent to the hair dryer bearing and causes the chamber to vibrate. The applicant believes that these vibration forces cause the hair dryer bearing to wear and May cause bearing failure. The applicant has tested other designs * many of which are shown in Figures 12A-12E * and they use aerodynamic forces distributed over a long period of time to reduce the reaction forces that are formed each time a blade passes near the edge of the support rod 44. One of the applicant's preferences A better anode support rod design is shown at 84A in Figure 6A. This design has a large mass that minimizes the temperature storage of the anode. The total mass of the anode and anode support rod is approximately 3.4 kg. At the same time, this design also includes a protruding piece 84B, which provides additional cooling of the anode. The applicant's tests indicate that both the muffler and the aerodynamic anode support rod tend to slightly reduce the gas flow. Because the gas flow is restricted, both The use of group improvements involves an analysis of compromise. For these reasons, two improvements are shown in Figure 6A instead of Figure 6. Pulse wave power system Four sets of pulse wave power module function description A better pulse wave power system is manufactured into four separate modules as shown in Figures 8A and 8B. Each module becomes an important part of the excimer laser system. And each module can be quickly replaced in the event of a component failure or periodic maintenance. The applicant designates these modules as: high-voltage power supply module 20, redirector module 40, compression head module 60, and laser chamber module 80. High-voltage power supply module The high-voltage power supply module 20 includes a set of 300-volt rectifiers 22 for converting a 208-volt three-phase power source from source 10 to 300-volt 19. This paper size is applicable to China National Standard (CNS) A4 specifications ( 210x297 mm) -------- Order ----- (Please read the precautions on the back before filling this page) Line 412891 A7 ___B7_ V. Description of the invention (//) DC = Inverter 24 conversion rectifier The output of 22 is a high frequency 300 volt pulse in the range of 100kHz to 200kHz. The frequency and conduction period of the inverter 24 are controlled by the HV power supply control board 21 to provide the system with the optimal output pulse energy adjustment. The output of the inverter 24 is boosted to approximately 1200 volts by the step-up transformer 26. The output of the transformer 26 is converted to 1200 volts DC by a rectifier 28. The rectifier 28 includes a set of standard bridge rectifier circuits 30 and a set of filter capacitors 32. The direct current electrical energy from the circuit 30 will be diverted to 8.1 # F in the diverter module 40. The C0 charging capacitor 42 is charged, which is guided by the HY power supply control board 21 that controls the operation of the inverter 24, as shown in FIG. 8A. The set point within the HV power supply control board 21 is set by the laser system control board 100. The reader should note that the pulse energy control of the laser system in the embodiment shown in Figure 8A It is provided by the power supply module 20. The electrical circuits in the steering gear 40 and the compression head 60 are only used to form the electrical pulse wave at a rate of 2,000 times per second to the electric power stored in the power supply module 20 on the charging capacitor 42 to amplify the pulse wave. The voltage and duration of the pulse are compressed in time.

Energy recovery This comparative embodiment has an electronic circuit The excess energy is collected into the charging capacitor 42. This circuit significantly reduces wasted energy and actually eliminates ripples in the laser chamber 80. The energy recovery circuit 57 includes an energy recovery inductor 58 and an energy recovery diode 59 , Connected in series with C. charging capacitor 42 "as shown in Figure 8B. Because the impedance of the pulse wave power system is not exactly matched to the impedance of the chamber and the impedance of the chamber changes many times during the pulse wave discharge The facts * cause a set of negative "reflections" to be generated from the main pulse, which is transmitted back from the chamber towards the front of the pulse wave generation system.

"Magnetic switching bias" In order to fully adopt the full BH curve swing of magnetic materials used in saturable inductors, a set of DC bias currents are provided so that each The inductor is reverse-saturated when the pulse wave is turned off by the switch 46. In the case of the saturable inductors 48 and 54 of the steering gear, this is used to provide an inversion of approximately 15A (compared to the direction of the normal pulse current) Bias current is achieved through the inductor. This bias current source is provided by the bias current 120 through the isolation inductor LB1. The actual current flows from the power supply through the ground connection of the diverter, through the main coil of the pulse wave transformer, via saturable inductor 54> via saturable inductor 48, and back to bias current source 120 via isolation inductor LBI, As indicated by arrow B1. In the case of a compression head saturable inductor, a bias current B2 of about 5 A is supplied from the second bias current source 126 via the isolation capacitor LB2. In the compression head, the current is separated and the main part B2-1 flows through the saturable inductor Lp-164 and passes through the isolation inductor LB3 to return to the second bias current source 26. The smaller component of the current B2-2 passes through the HV cable connecting the compression head 60 and the redirector 40 to the ground via the secondary coil of the pulse wave transformer, and returns to the second bias current source 126 via the bias resistor. This second smaller current is used to bias the pulse transformer so that it is also reset during pulse wave operation. The amount of current divided into two branches is determined by the resistance of each channel and adjusted so that each channel receives the correct amount of bias current. 25 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) --------: ------------- Order ----- (please first Read the notes on the back and fill in this page) Line 4- 412891 A7 ___ B7 _._ V. Description of the current) In this embodiment, the current flows from a standard three-phase power source 10 through the system to the ground of the electrode and the overriding electrode 84. Pulse wave energy flow is called "forward flow" and this direction is called forward direction. When we say that an electrical component such as a saturable inductor is forwarded, we mean that it is biased into a saturated state and conducts "pulse energy" in the direction toward the electrode. When it is conducting in the reverse direction, it is biased into a saturation state and conducts energy away from the electrode toward the charging capacitor. The actual direction of the current (or electron flow) through the system depends on its location within the system. The direction of the current will then be explained to eliminate possible doubts. Refer to Figures 8A and 8B, C in this preferred embodiment. The capacitor 42 is charged (for example) positive 700 volts so that when the switch 46 is turned off, current flows from the capacitor 42 via the inductor 48 in the direction of C, capacitor 52 (the electrons actually flow in the opposite direction). Similarly The current flows from the Ci capacitor 52 to the ground through the main side of the pulse transformer 56. Therefore, the direction of current and pulse energy is the same as from the charging capacitor 42 to the pulse transformer 56. As shown below in the "pulse transformer__title" Explanation of the part * The current in the main circuit and the secondary circuit of the pulse transformer 56 is directed to ground. The result is when it is at the beginning of the discharge (which represents the main part of the discharge, generally about 80%) ) When the current between the pulse transformer 56 and the electrode is away from the electrode toward the transformer 56. Therefore, the direction of the electron flow when the main discharge is reached from the ground temporarily via the secondary coil of the pulse transformer 56 C ρ .1 Capacitor 62, via inductor 64, temporarily reaches Cp capacitor 82, via inductor 81, via electrode 84 (this is referred to as discharge 26) This paper applies to Yin Guoguo Home Standard (CNS) A4 Specification = < 297 mm) (Please read the notes on the back before filling this page)! — Order ·! -Line, printed by the Intellectual Property Bureau Staff Consumer Cooperatives of the Ministry of Economic Affairs 412891 A7 B7 Ministry of Economic Affairs Printed by the Intellectual Property Bureau's Consumer Cooperative (5) (Explanation (M) cathode), via the discharge plasma, via electrode 83 and back to ground. Therefore, the electron current flows between the pulse wave transformer 56 and the electrodes 84 and 83 in the same direction as the energy of the pulse wave when mainly discharged. Immediately after the discharge, the current and electron flow are reversed and the reverse electron flow rises from the ground point via the ground electrode 84, via the discharge space between the electrodes to the electrode 83 and via the transformer 56 to ground. The "main" loop current of the transformer 56 is generated via the reverse electron flow channel of the transformer 56 from which the electron current flows from the ground point via the "main" side of the pulse transformer 56 (same direction as the main pulse current) and Finally, charge Co as shown in Figure 8F2. The negative charge on Cc is reversed as shown in circle 8F2 and has been explained above in the section entitled Energy Recovery .. Detailed description of the pulse wave power supply components A more detailed circuit diagram of the power supply part of the preferred embodiment is shown in Figure 8C. As indicated in Figure 8C, the rectifier 22 is a 6-pulse phase control rectifier with + 150v to -150V DC output. 24 is actually three sets of inverters 24A, 24B, and 24C. When the voltage on the Cfl charging capacitor 42 of 8.1 is less than the command voltage of 50 volts, the inverters 24B and 24 C are cut off and when at <^ 42 When the above voltage is slightly higher than the command voltage > Inverter 24A is cut off. This step reduces the charging rate before the end of charging. Stepper transformers 26A, 26B and 26C are each rated at 7kw and convert their voltage to 12 0 Volts AC.

The isolator 56C isolates the positive end of each spool from the negative end of an adjacent line spool. Between the bobbin flanges is a hollow 11/16 inch long cylinder with a wall thickness of 0.875OD and approximately 1/32 inch-the bobbin is one inch wide · 0.7 mils thick Metglas ™ 2605S3A and 0.1 mils The thick polyester film is wound until the OD of the isolated Metglas ™ winding is 2.24 inches.

The secondary coil of the transformer is a single stainless steel rod mounted in an electrical glass immediately inside the insulating tube. The winding is divided into four parts, as shown in SD 圊. The stainless steel secondary coil shown at 56D in Fig. 8D is grounded at 56E to a ground wire on the printed circuit board and the high-voltage terminal is shown at 56F. As shown above, a 700 volt pulse between the positive and negative terminals of the primary winding will produce a negative 16,100 volt pulse at terminal 56F on the secondary side, resulting in a 1 to 23 voltage transition.

Description of the invention) It states that its composition is 0.1% fluorine and the remainder is helium. The% fluorine represents the volume of approximately 0.0023 liters or 2.3 milliliters of fluorine at 4 atmospheric pressure. In terms of mass, the approximate amount of fluorine in the laser container is about 110 mg. Partial pressure of pure fluorine is about 411Pa, pure fluorine (corresponding to about 41Kpa of 1% fluorine mixture). When the laser is normally operated with an expensive factor of about 40% (typical photographic plate laser), the consumption rate of fluorine is about 4.5 mg per hour (corresponding to about 4% of fluorine in the chamber per hour). In terms of the partial pressure of pure fluorine > The normal consumption rate of fluorine is about 16 hours per hour 16Pa »To compensate this consumption with a 1% fluorine gas mixture, a volumetric mixture equivalent to approximately 1.6kPa per hour is added to the chamber. The rate of laser fluorine consumption is not constant. If the laser fan is operated but no laser is generated, the fluorine consumption rate is approximately halved. If the fan is turned off, the fluorine consumption rate is reduced to about 1/4 of the 40% expensive factor consumption rate " At a 100% liability factor, the consumption rate is double the consumption rate of the 40% expensive factor factor '' gas replacement The process described above essentially replaces the consumed fluorine almost continuously. Because the fluorine gas source is only 1% fluorine > it also replaces some of the helium in the chamber almost continuously. Although even a portion of the laser gas is roughly continuously replaced, operation in this mode will result in pollution that reduces laser efficiency generated in the laser gas. This reduced efficiency requires increased voltage and / or increased fluorine concentration to maintain the required pulse wave energy. Therefore, the general recommendation of prior art systems is that the laser is periodically turned off to achieve a substantially complete gas exchange. This roughly complete gas exchange is called recharging. These periods can be based on the number of laser pulses. 32 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm). — — — — — — — — — — — — ---- II-^ i — — — — — — — (Please read the precautions on the back before filling out this page) Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Consumption Cooperative 412891 A7 ____B7____ 5. Description of the invention (such as) Item 1 For example between recharge 100 , 000,000 sets of pulses, and it is determined that the “recharge time” can also be determined based on the combination of the time elapsed during the last recharge last time or the pulse wave and the time of the last recharge time. It can be determined based on the amplitude of the charging voltage required to achieve the desired output at a particular fluorine concentration. After recharging, a new "quotient" test is best performed. At the same time, the benefits test should be performed periodically between charges, so if the benefits change, the operator will know where the new benefits are located. The system in Figure 16 can be used as follows to achieve recharge. By closing valves 510, 506, 515, 512, 517, and 504 and opening valves 506 and 512, the vacuum pump 513 can be operated and the laser chamber can be pumped down to an absolute pressure of less than 13 kPa. (A direct pumping down line can be provided between the chamber 1 and the vacuum pump 513 to allow fast pumping). Valve 512 is closed. Valve 515 is opened and 100% helium buffer gas from a buffer gas bottle 516 is added to the chamber to fill it to a pressure equivalent to 262 kPa at 50 ° C. (Note that in a 20 · 3 liter laser chamber, the temperature correction can be corrected by shifting the chamber temperature from 50 ° C using the ΔP / ΔΤ correction of IkPa / t. Therefore, if the chamber temperature is 23 ° C, it will be charged to 247kPa. Valve 517 is closed and valve 515 is opened and a mixture of 1¼ fluorine, 99% helium from the halogen-rich gas bottle 514 is added to the chamber 1 to charge it to equal Effective at a pressure of 290kPa at ° C.

V. Invention Description (3) This type significantly reduces the changes in the previous technology of pulse energy and total integrated array energy. The following describes improved equipment and software and better processing procedures to reduce energy sum and array dose variation. As described in the background section of the explanation, the array mode is a typical mode of excimer laser operation > It uses a light source that is a stepping machine in the integrated circuit of a photoengraving product. In this mode, the laser operation generates an "array" of pulse waves at a rate of 1000 Hz, and lasts about 110 milliseconds to generate 110 pulses to illuminate the ~ portion of the crystal. After the array, the stepper Move the wafer and the mask. Once the movement is completed, it usually takes a few tenths of a second to make the laser produce another set of 1 10 pulse wave arrays = Therefore, the normal operation is an array of about 110 milliseconds followed by a few tenths of a second. Stop time. In each case, a longer stop time period will be provided so that other operations can be performed. This basic processing procedure continues 24 hours a day, 7 days a week, and lasts for many months. The laser generally generates several hundred per day. Wan array. In the above array mode, it is usually important that each part of the wafer receives the same luminous energy in each array. At the same time, the wafer maker hopes that the pulse-to-pulse variation is minimized. The preferred embodiment uses equipment and software to achieve these goals. It monitors the energy of each pulse wave (pulse wave N-丨) and then controls the energy of the next pulse wave (pulse wave N) according to the following results: 1) The pulse wave N-1 Set Comparison result of energy and target pulse wave energy 2) Comparison result of cumulative dose through pulse wave N-1 array and target pulse wave dose through pulse wave N-1. In a typical F2 excimer laser, we have discussed First, the energy of the 30-40 pulse wave is generally shorter than that of the remaining arrays due to the transient effects in the laser gas.

Approximately 40ms after the pulse, the energy of the pulse with a fixed voltage is relatively fixed. In dealing with these early pairs, the applicant divided the array into two sets of time-direction regions, the first region (containing a number of previous pulses, for example, 40 The pulse wave) is called the __K " zone and the second zone (including the pulse wave following the K zone) is referred to as the zone by the applicant in this description. This embodiment of the present invention uses a prior art excimer laser device for Pulse wave energy control. The pulse wave energy of each pulse wave of each array is measured by the photodiode 92 Measurement • As shown in Figure 8A. All response time of this photodiode and its sample and hold circuit, including the time required to reset the circuit It is stored within a few microseconds after the end of the pulse and this signal is read six times on average and is stored by the computer controller 22 approximately 1.0 microseconds after the start of the pulse. The accumulated energy is called the array dose 値. The computer controller uses signals representing the pulse wave energy of the pulse wave N and the target pulse wave energy and the array dose 値 to specify the high voltage of the pulse wave N + 1. This calculation takes about 200 microseconds. When the high voltage of N + 1 is determined, the computer controller sends a set of signals to the high voltage command (VCMD) 120 of the high voltage power supply, as shown in Figure 9 • To create a pulse wave N + 1 that takes several microseconds Charging voltage. The computer controller 22 commands the high-voltage power supply to capacitor C. Charge to the specified voltage. (At high repetition rates exceeding 2000 Hz, it may be necessary to start charging before the calculation is completed.) When a trigger signal from pulse wave N + 1 of trigger circuit 13 is received 0.5 milliseconds after the trigger signal from pulse wave N, As shown in Figure 2, this charging takes about 250 microseconds, so C.

For example, dE / dV can be determined in the L and K regions. Dithering can occur once per array, or multiple times. The jitter order can be performed at a fixed number of pulses j as described above, or it can be started for any number of selected pulses that change from one array to the next array. The reader should know that A, B and C are convergence factors , Which can have many others. A higher 値 than specified above can provide faster convergence 'but can lead to increased instability.

In the case of no dose correction, B can be zero; however, A should not be zero 'because it provides a damping term to the dose delivery part of the algorithm. If the determined dE / dV ratio becomes too small, the above algorithm can lead to overcorrection. Therefore, in the preferred technique, if the sum of the energy sum exceeds the threshold, dE / dV is arbitrarily doubled. The original values of V and dE / dV are provided to the first pulse of the array. D is set to zero at the beginning of each array.

These data can be used to determine dE / dV as a function of V at a fixed pulse energy. Readers should note that the differences in dE / dV do not include considerable uncertainty> because the components of 値 are significant measurement differences with significant uncertainties '' but • averaging a large number of dE / dV 値 can reduce these Uncertainty. The dithering operation to determine dE / dV does not have to be formed in each array and can be formed periodically, for example, once per M array. Or the dE / dV measurement can be calculated by the computer (replaced or the dE / dV) can be manually inserted by the operator of the previous pulse wave for the calculation of VN + 1. In addition, the actual measurement can be used in this control system. . At the same time, ^ 11 値 can be calculated from the specified 値, rather than the actual measurement 値 in the above embodiment. Another obvious method is to use the measurement voltage 値. Ετ is generally fixed, such as 10m, but it does not have to be constant. For example, the Et of the last ten sets of pulses may be smaller than the nominal pulse energy, so that the percentage of these pulses offset from the target Et will have a smaller effect on the integrated pulse dose.

Prototype unit 42 This paper size is in accordance with Chinese national standard (CNSXA4 specification (210 X 297 mm) 412891 A7 _B7____ V. Description of invention) A prototype F2 laser system unit was established and tested by the applicant and their staff. This prototype laser is largely based on the current production KrF and ArF laser excimer laser systems, which have many important improvements over the previous technology, which uses a high-efficiency chamber and solid-state pulsed power excitation. The discharge is pre-ionized by corona In order to minimize gas pollution, the entire optical beam channel is purged with nitrogen to avoid light being absorbed by oxygen and damage to optical components. All the resonator optics are added to the laser chamber with an angle chamber window. The gas mixture was 0.1% fluorine at 4 atmospheric pressures of helium and the electrode gap was reduced to 10 mm. In this module, the applicant has successfully demonstrated the main parameters for standard photoengraving fluorine lasers | which have only a few direct changes to the currently developed ArF lasers. Test results The test results of the prototype unit are described below. This laser power source is measured by a set of standard power supply measuring devices and interacts with a set of piezoelectric Joule meters. The effect of the red atomic fluorine laser is subtracted and is usually less than 1% of the total energy. The red radiation can be measured by exhausting the beam feeder tube to the air, which strongly absorbs light of 5 7 η m. The laser wavelength in this prototype unit was adjusted in a single-line mode at 157.6nm using a set of two external prisms. The laser can also be adjusted to a 157.5nm transfer line with reduced efficiency. The transition is not visible at 156.7nm. The laser spectrum recorded with a 2 meter lobin YvonVUV spectrometer indicates a limited measurement line width of 6 p m. 43 This paper size applies to Chinese national standard (CNS > A4 size (210 X 297 mm) (Please read the precautions on the back before filling this page)) -Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 412891 A7 _B7_ V. Description of the invention (w) In a wide band (or multi-line) operation at a repeat rate of 1000 Hz Get a maximum power of 12W. The power supply linearly shows no sign of saturation as the repetition rate increases. The behavior in single-line mode is similar, but the energy is 1/3. The decrease in energy is due to the large cavity length in current radon devices Increased and can be significantly reduced. In array mode, 3—sigma 3% σ stability is recorded. Only the output can be set to start the array transient. This is advantageously compared to ArF lasers, which exhibit greater energy Instability and the airflow about the transient state of the array. Therefore, we can conclude that the production of a fluorophotographic plate laser will have better energy stability than the current ArF laser. The integral square pulse lasts 30ns, which is close to the ArF laser. performance Careful selection of laser chamber materials and the use of pre-ionization of corona discharge to induce laser operation without the need for cryogenic purification and the need for halogen spraying for many hours as well as a 3 MW emission with a small energy reduction. The relationship of the coverage rate is shown at the top of the graph. The bottom part of graph 10A shows that increasing the repetition rate beyond 10002 reduces the pulse energy slightly. The laser power increases linearly with the repetition rate to 15W power. (At 1kHz) and to about 19W power (at 2kHz). Based on this linear relationship, we can assume that the fluorine laser can be further adjusted to operate at many kilohertz, and assume that the airflow is adjusted accordingly. Because the applicant uses helium as Buffer gas requires only a part of the power of a standard neon-based laser hair dryer and therefore does not show the limitation of higher flow rates. A good measurement of energy stability is obtained by observing the energy transients in the array mode. Therefore The laser is repeatedly excited in an array and the average energy at each pulse position in the array is recorded.

Description of Invention (4Z) The number of each pulse in the array is the average change in energy from the array to the array. Calculations. The generated energy and stability curves for fluorine lasers, and the comparison of linear narrow-band ArF lasers are shown in Figures 10B1 and 10B2. The fluorine laser has only a small amount of energy change over the 120 arrays. Energy stability The performance exhibits an initial increase at the beginning of the array and then stabilizes above the 3σ level of about 3%. In contrast, ArF lasers have large transfers in energy and 3σ instability of about 7%. ArF lasers have a distribution stability of 0.5% in 60 sets of pulse windows *. Therefore, fluorine lasers are expected to have at least the same distribution stability. The 苐 10C plot contains pulse energy and 3 σ 1000 at 1000Hz and 1900Hz. A wide-band fluorine laser spectrum recorded with a νυν spectrometer is shown in Figures 10D1 and 10D2. It can be clearly seen that 87% of the laser energy at two groups of transfer lines at 157.52nm and 157.63nm is placed in the longer wavelength line of 157.63nm. The transfer at 156.7nm is not visible. The single-line mode operation at 157.63nm is achieved by adjusting a set of two external chirps. The laser can also be adjusted to a transfer line of 157.52 nm, but with reduced efficiency. Figures 10D1 and 10D2 also show an expanded view of the ray at 157,63 nm. 1.14pmFWHM and 2.35pm 95% of the convolution line widths are measured Applications. The laser power for a single-line laser has the same linear increase in repeatability results as a wideband laser. However, the maximum power in this initial test was limited to 4W. This reduced output power is due to the reflection loss in line-selective optics and the overall length of 45 paper standards applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -------- i — * J1 (Please read the precautions on the back before filling this page) nnn line, printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs ¥?

It can be seen in Figure 10F that after four million laser launches, the laser The reduction of the radio power is less than 20%, which is at least as good as ArF laser. From the previous experience of ArF laser, we can use periodic fluorine injection and therefore expect a gas life of about 25 million shots. This is due to the choice of Results of matching materials in the chamber and using corona preionization. For KrF and ArF lasers, a direct correlation between fluorine consumption and chamber life was established previously. Therefore, we can estimate fluorine The life of the laser chamber is the same as that of ArF laser. The bottom graph of Figure 15A shows the pulse wave energy relative to the F2 concentration and the top graph shows the maximum pulse wave repetition rate, both A blower speed of 250 rpm. The top graph in Figure 15B shows the pulse shape of the time function, which indicates a FWHM of 16ns. And the bottom graph shows the integral square pulse width is about 37ns. Although this F2 laser has been referenced to a specific implementation For example, it should be understood that various changes and modifications can be made. For example, many different embodiments are discussed in the patent applications listed in the first part of this description, all of which are listed here for reference. Calibrator output couplers can be Use to provide another 46 narrow lines. Applicable to China National Standard (CNS) A4 specifications (210 X 297 public love).
