- 102 denotes a loading and unloading station which has three platforms 104 for cassettes 106 equipped with wafers. The loading and unloading station will not be discussed in detail.
- a first robot 108 is used to remove the wafers from the cassettes 106, the robot first placing each wafer on a cassette identification device 110 or holding it therein.
- the robot 108 is designed for handling dry wafers. It removes the wafers from the storage compartments of the cassettes and transfers them to the identification device 110 (a wafer 112 is shown in the recognition device 110). The robot 108 then conveys the wafer 112 to a transfer point 114, at which a layer thickness measuring device 116 is also arranged.
- Another robot 118 is arranged approximately centrally in the clean room 100, with the aid of which the wafer is transferred from the transfer point 114 to an intermediate station 120 is promoted.
- the intermediate station 120 has the storage surfaces 122 to 128, which are arranged on a rotatable carrier.
- Polishing plates 130 and 132 are rotatably driven on the sides opposite the carrier.
- Each polishing plate 130 has two polishing heads 134, 136 and 138, 140.
- the polishing heads can be moved linearly between the positions shown in FIG. 1 in a position above a storage surface 122 to 128. They are arranged to be vertically adjustable and serve to transport the wafers and hold them against the polishing plates 130, 132 so that they are polished there by the CMP method.
- Two processing and cleaning stations 142, 144 are arranged between the polishing plate 130 and the intermediate station 120. Similar cleaning stations 146, 148 are arranged between the intermediate station 120 and the polishing plate 132.
- the processing and cleaning stations can be pivoted between a position as shown in FIG. 1 and a position in which they are aligned with a storage surface.
- the stations 142 to 148 are therefore spatially arranged above the storage surfaces 122 to 128, but can be run over by the polishing heads 134 to 140.

- the entire polishing device including the intermediate station 120 and the dressing device 150 or 152, is arranged in a separate compartment within the clean room 100.
- a cleaning and drying device is arranged in another compartment of the clean room 100. It contains a main cleaning station 154 and a final cleaning station 156, into which the wafers are fed from an input station 158 get out.
- the wafers are put into the input station by the robot 118 and are conveyed from there via a V-shaped transport path 160, which is preferably a water transport, through cleaning arrangements.
- the individual stations are discussed in detail below.
- the cleaned wafers arrive at a stop point 162, which is arranged approximately in the rounded apex of the V-shaped path, before they are conveyed to a rinsing and drying spinner 162a with the aid of a robot arranged at 164.
- the cleaned wafer is then transported back from the rinsing and drying spinner 162a into a ready-made cassette with the aid of the robot 108. It can be seen that the robot 108 only attacks and transports dry wafers, while the robot 118 only attacks and transports wet wafers.
- the legs of the V-shaped web are such that the second leg runs approximately parallel to the wall of the clean room 100, while the first leg with the main and final cleaning stations 154, 156 is directed obliquely inwards into the clean room. This results in an extremely space-saving arrangement.
- the V-shape also has the advantage that the one-time deflection with respect to the wafer is extremely gentle on the edges.
- the input station 158 is constructed identically. It has five transport rollers 10.
- a lifting device 12 picks up a wafer 112 after it has been polished and lowers it onto the rollers 10 for transport to the main cleaning station 154.
- the wafer reaches the final cleaning station 156 via a rinse lock 14 and from there to one Megasonic station 16 (in Fig. 2).
- the wafer moves from the final cleaning station 156 to a stop station 18 and then to a removal station 20, in order to be brought from there with the robot 164 to the drying station 162a.
- a water cushion transport section 22 is provided between the final cleaning station 156 or the megasonic station 16 and the removal station 20.
- the final cleaning station 156 is missing in FIGS. 4 and 5, and the megasonic station 16 is provided instead in FIG. 4.
- Fig. 5 only the main cleaning station 154 is provided.
- the parts described are arranged within an elongated housing 24, on the ceiling of which spray nozzles 26 are partially attached. In any case, the wafers are moistened on all transport and stopping lines.
- FIGS. 2 to 5 schematically illustrated device parts will be discussed below.
- the input station 158 is shown in more detail in FIG. 6.
- the rollers 10, which consist of soft, absorbent plastic material that is applied to a hard roller core, are driven together at a predetermined speed by a drive device, which will not be discussed in detail.
- the drive device is controlled by a control device, not shown.
- the storage of the rollers is also not described.
- Three holding pins extend between the rollers 10 and are designed to grip and hold a wafer 112 at the edge.
- the holding pins 28 are attached to a platform 30, which can be adjusted in height with the aid of a lifting device 32. By lowering the holding pins 28, the wafer 112 can therefore be lowered onto the rollers 10.
- the rollers are driven so that the wafer is transported in the direction of arrow 34.
- liquid is sprayed onto the arrangement with the aid of the nozzles 26, preferably DI water.
- a detector 36 determines whether there is a wafer in the input station 158.
- the detector 36 is connected to the control device, not shown
- the main cleaning station 154 has seven pairs of rollers, each pair having an upper and a lower roller.
- the first, third, fifth and seventh pair of rollers are driven in one direction of rotation such that a wafer guided between them is transported in the conveying direction.
- the remaining pairs of rollers, which are designated 38 in total, are driven in the opposite direction.
- the rollers are made of liquid-absorbing soft plastic material.
- the frame 40 includes an upper plate 44 which is suspended from a stationary plate 48 by means of soft elastic elements 46. Adjustment cylinders 50 act between the plate 48 and the plate 44 in order to press the frame 40 against the accommodated wafer 112 with a predetermined pressing pressure. The contact pressure is independent of the thickness of the wafer 112. Below the roller pairs there is a collecting trough 52 for the liquid which is instilled onto the rollers. This will be discussed further below. In addition, there is an exhaust duct 54 at the lower end of the housing 56, in which the parts described are housed.
- the housing is essentially closed and has a lateral insertion opening 58 and a lateral outlet opening 60 for the wafer.
- Electric drive motors and gears are designed so that the rollers of the roller pairs 38 can rotate at different speeds in different directions, the majority of the roller pairs as Transport rollers accomplish the transport of the wafer, while the remaining pairs of rollers as cleaning rollers rotate in the opposite direction to achieve an optimal cleaning effect.
- the transport and cleaning rollers can be driven with the same or with a different number of revolutions.
- Each cleaning roller is assigned a media distributor, which is shown in perspective in FIG. 8. It is generally designated 62 and has a nozzle 64 which is connected to a media supply.
- the nozzle 64 is coupled to a pendulum 66, which is actuated by a heart curve 68.
- the heart curve 68 is rotated by a drive, not shown. In this way it is achieved that the movement of the nozzle 64 above the rollers in its longitudinal direction is uniform.
- the residence time of the nozzle 64 over each roller section is the same. This results in a lower consumption of chemicals and cleaning agents.
- FIG. 10 schematically indicates how different chemicals or media can be supplied simultaneously in the desired mixing ratio.
- three sources for media are shown at 70, 72 and 74, respectively. They are connected via a volume flow meter 72 and a control valve 74 to a static mixer 76, from which the supply then z. B. to the nozzle 64, for example via a metering pump.
- the flow meter 72 is also a controller so that the desired predetermined amount of media reaches the mixer 76 from the media sources 70 to 74.
- the rinse lock 14 has a pair of rollers 80 which is driven by a suitable drive device such that the rollers move counter to the transport direction of the wafer 112, which is from right to left in FIG. 9. As a result, they produce a cleaning action like the cleaning roller pairs 38 of the main cleaning station 154.
- the rollers of the roller pair 80 are also made of soft, liquid-absorbing plastic material. Nozzles 82 above and below the wafer 112 initially serve to rinse the wafer and remove the material that is still on the wafer 112 after cleaning or treatment.
- the rollers 80 then provide final cleaning. This prevents transmission of the medium used in the main cleaning station 154 to the final cleaning station 156.
- the length of the rinse lock 14 is less than the length of the wafer 112. As a result, the wafer 112 is transported through the rinse lock 14 solely by the transport rollers from the main and final cleaning stations.
- the rinse lock also includes a floor pan (not shown in detail) and a drain port 84.
- a Megasonic station 16 can be used in addition or as an alternative to a final cleaning.
- the wafers are cleaned of very small particles (e.g. ⁇ 0.5 ⁇ m).
- FIG. 11 shows a single-chamber arrangement of a megasonic station 16. It has holding pins 86 which stop the incoming wafer 112 (from the left in FIG. 11) and then hold it at at least three edge points. The transport takes place in FIG. 2 via the transport rollers of the final cleaning station 156 and in the embodiment according to FIG. 4 through the transport rollers of the main cleaning station 154. Station 16 has a tube 90 arranged with outlet openings, the direction of which is directed obliquely towards linlcs, so that a wafer 112 can be transported further to the left by means of a directed liquid film when it is released by the lifting and lowering holding pins 86.
- trough 92 which can be raised by means of a lifting device 94 and which receives a coupling liquid for the ultrasound treatment of the wafer 112. After the flooding, the wafer is in a horizontal position in a liquid-filled area, the height of the liquid being below and above the wafer 112 is approximately the same size.
- An upper and a lower Megasonic transducer are provided (not shown in detail), which can be attached to fixed pool walls.
- a Megasonic nozzle system can also be provided.
- the workpiece is held on a rotor at the edge. During the rotation of the wafer, it is run over radially by a Megasonic nozzle unit, whereby the entire surface of the workpiece is reached. The cleaning fluid is fed through the Megasonic nozzle, which automatically results in the sound coupling between the transducer and the workpiece.
- the transport takes place via a water cushion in the channel housing 24.
- the forward transport takes place solely by a directed inflow of water.
- the nozzles used here are e.g. B. realized by directed inflow channels. Due to the water cushion and the additional rinsing, both sides of the wafer are permanently rinsed during transport. DI water is typically used as the rinsing liquid. Diluted chemicals can also be used for special applications.
- the main outflow for the rinsing liquid is preferably at the end of the channel 24. However, outflows can also be interposed in order to ensure improved particle and chemical drainage (not shown).
- a stop station 18 is provided, which is located in the water cushion transport route 22.
- the previously cleaned wafer is stopped in the stop station 18.
- the stop station can e.g. B. can be realized by holding pins, which is driven by a lifting device, not specified, in the transport path of the wafer.
- a detector (not shown) is provided, which checks whether there is a wafer at this point.
- the transport of a wafer 112 from the input station 158 is only released when the stop station 18 is not occupied by a wafer. As already mentioned, this is controlled Operations via the control device, not shown. In the device according to FIG. 2, the megasonic unit 16 takes over the buffer function, so that a separate stop station is not required.
- the wafer is stopped and held by holding pins of a removal station 20, the holding pins being able to be raised with the aid of a lifting device 98 in order to keep the wafer 112 ready for removal.
- the removal takes place with the aid of the robot 164, which can lift the wafer and at the same time transport it to the drying station 162a.
- a detector for wafers 112 is also assigned to the removal station 20. The stop station 18 only allows a wafer to be transported further if no wafer is accommodated in the removal station 20.
- the drying station 162a contains a tower-like housing into which a wafer is moved by the robot 164 via a lock (not shown).
- a rinse-dryer which is used to set the wafer in rotation at speeds of up to 2000 rpm. It is driven by an electric motor. Two phases are carried out in the drying station, namely the process steps of rinsing and dry spinning. Different speeds can be set here.
- the wafers are held on the rotor using holding pins.
- Media supply lines can be used to apply flushing liquids, gases or vapors to the top of the workpiece and also to the underside of the workpiece.
- Typical rinsing liquid is DI water.
- Typical gases are mixtures of an inert carrier gas such as. B. nitrogen and a vapor of a water-soluble, surface tension reducing substance, preferably a short-chain alcohol such as isopropanol.
