Description of the Invention (1) [Field of Invention] The present invention relates to a semiconductor packaging technology, and in particular, to a photosensitive semiconductor packaging process capable of preventing overflow, which can be used to package a photosensitive semiconductor Zhao chip, for example, is an image sensor chip or a programmable read-only memory (EPROM) chip that can sense ultraviolet light and can be packaged with gel. During the mold casting process, the occurrence of glue overflow on the guide leg is prevented. [Background of the Invention] Semiconductor packaging technology can accommodate one or more semiconductor wafers in a single packaging gel to facilitate the integration of the wafer onto a printed circuit board. Generally speaking, the packaging colloids are mostly made of opaque resin materials. But for photosensitive wafers, such as image sensor wafers or programmable read-only memory chips that can withstand ultraviolet light, It is necessary for the packaged chip to be able to sense external light. Therefore, a photosensitive wafer must use a special packaging technology for packaging. A photosensitive wafer packaging method commonly used in the conventional technology is to first form a packaging colloid with a central cavity portion; then stick the crystal through this central cavity portion. And wire welding process; finally, a transparent cover sheet is fixed to the opening of the central hollow part, and the packaging of the photosensitive chip is completed. The encapsulated photosensitive chip can sense external light through the transparent cover. However, one of the manufacturing process problems of the above-mentioned photosensitive semiconductor packaging process is that during the molding of the packaging colloid, it is easy to cause an overflow of glue on the portion of the guide frame used to adhere the chip and the solder wire, resulting in subsequent wafer adhesion. Placement and wire bonding produce poor quality results. This process problem has already been approved.

The first embodiment of the semiconductor packaging process. Please refer to FIG. 1A first. The first step of the photosensitive semiconductor packaging process of the present invention is to prefabricate a guide frame 100, a support block 110, and a mold set 12 0. The guide frame 100 has an adhesive The crystal base 101 and a guide leg 102 (this guide leg actually has a plurality of guide legs, but not all of them can be shown in the side view of FIG. 1A). In this embodiment, the supporting block 110 is an electrically insulating block having a flat upper surface 111 and a lower surface Π2 protruding from the chattering portion, and has a predetermined width F and a predetermined height. The predetermined width 酽 must cover at least the entire die mount 101 and the inner end of the guide leg portion 102, and the predetermined height ruler must be approximately equal to the support height of the die mount 101 of the guide foot stand 〇〇〇. The mold set 120 includes an upper plug-in module 121 and a lower cavity module 122 ', wherein the upper plug-in module 121 is formed with a side wall cavity structure 12U (this side wall cavity structure 121a will be used to form in subsequent regulations) The side wall part of the encapsulating colloid) 'and the bottom cavity module 122 is formed with a base cavity structure 122 a (this base cavity structure 122 a will be used in subsequent processes in accordance with this paper standard to Chinese National Standard (CNS) A4 Specifications (210x297 mm) 15975 ------------- Installation -------- Order --- I ----- line (Please read the precautions on the back before filling (冩 Page) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 7 447097 A7 __________ V. Description of the Invention (7) to form the base part of the package kick body). The depth of the base cavity structure 122a must be approximately equal to the height of the support block no. Please refer to the circle 1B. The next step is to accommodate the support block 110 in the cavity structure 122a of the base of the lower cavity module 122; then, the entire sticky crystal base 101 and the guide leg 1 of the guide frame 100 〇2 The back of the inner end is placed on the upper surface of the supporting block 11; then, the upper plug-in module 121 is pressed down on the leg guide 100. Since the height of the support block 11 is approximately equal to the depth of the cavity structure I22a of the base, the support block 11 and the upper plug-in module 121 can work together to clamp the entire die mount 101 and the guide of the guide 100. The inner end of the leg portion 102 can achieve an air-tight clamping effect. Then, a molding process can be performed, so that a molding material, such as resin, is filled into the side wall cavity structure 12u of the upper plug-in module 121, and simultaneously filled into the base of the lower cavity module 122. The cavity portion 122 a is not a hollow portion occupied by the support block no. In this die-turning process, 'the entire inner die end of the guide frame 100 and the guide leg are air-tightly clamped between the support block 110 and the upper plug-in module 121, so the die-casting process The resin used is difficult to spill on these parts, that is, there will be no overflow of glue. Β Please refer to Figure 1C 'The next step is to remove the upper plug-in module 121 and the lower cavity module i22, that is, It can be made into an encapsulant 13. In the above-mentioned mold casting process, the resin filled in the side wall cavity structure 121a of the upper plug-in module 121 is formed into the sealing colloid 13 and the upper side wall portion 131 is filled into the base of the lower cavity module 122. The resin in the cavity structure forms the lower base portion 132 of the encapsulant 130.

Please refer to FIG. 1D. The next step is to perform a die attachment process, whereby a photosensitive semiconductor chip 140, such as an image sensor chip or a programmable read-only sensor that can sense ultraviolet light, is performed. The memory chip is pasted through the central cavity portion 13la of the upper side wall portion 13 of the encapsulation gel 13 and adhered to the front surface of the die mount 〇1 of the guide frame 10. Then a wire bonding process is performed. The semiconductor chip 14 is electrically connected to the inner end of the guide pin portion 102 of the lead frame 100 by using a wire group 1 50 ′, such as a wire made of gold. In the above-mentioned bonding die and wire welding process, because the steps described in the figure will prevent the glue overflow phenomenon from occurring on the entire front of the die attach base 101 and the inner end of the guide pin 102 of the guide frame 100, The finished die bonding and wire welding have high reliability.

Invention Explanation (10) The upper surface is fixed in advance to the bottom surface of the inner end of the guide leg portion 102 and the guide base portion 102 by an adhesive 320 in advance. During the molding process of the encapsulant 130, the placement position of the support block 310 is exactly the same as the support block no shown in FIG. 1B. Therefore, the support block 310 can work together with the upper plug-in module 121 to generate air. The entire sticky crystal base 101 and the inner end of the guide leg portion 102 of the leg guide 100 are tightly clamped, thereby preventing glue overflow. However, since the foot guide 100 has been fixed to the support block 310 by using adhesive 32, the foot guide 100 will not be caused when the upper plug-in module 丨 21 is pressed onto the guide foot 100. A sliding phenomenon occurs at 100; that is, the entire sticky crystal base 101 of the guide leg holder 100 and the inner end of the guide leg portion 102 have a more stable air-tight clamping effect. [Conclusion] In summary, the present invention provides a novel photosensitive semiconductor packaging process, which can be used to package a photosensitive semiconductor wafer, such as an image sensor chip or a programmable ultraviolet light sensor. The read-only memory chip can be used in the molding process of the encapsulation gel to prevent knee overflow on the guide. The feature of the present invention is that a supporting block with a specific structural shape is used in combination with a mold set used in the mold casting process to air-tightly clamp the guide leg portion that cannot be caused by overflowing glue, thereby Prevent the occurrence of glue overflow on these guides. Compared with the conventional technology, since the present invention does not need to use expensive organic polymer coating materials and cleaning solvents to remove the overflow glue, the present invention has better cost-effectiveness and environmental protection benefits.
