Known technology 10 In the past, the well-known QFN type semiconductor devices did not have leads protruding outside the package side. Instead, the exposed edges of the lower edge of the package were used to expose the leads electrically connected to the mother substrate. The resin sealing system of the aforementioned semiconductor device is, for example, bonding a semiconductor wafer 3 to a die pad 2 of a lead frame 1 (FIG. 12A), and bonding the semiconductor wafer 15 3 and the lead 4 of the lead frame 1 with a wire 5 (Figure 12B), the upper mold 6 and the lower mold 7 clamp the lead frame 1 to form a hole 6a (Figure 12C), and inject resin 8 through the hole 6a to obtain a semiconductor device (Figures 13A and 13B) . However, FIGS. 13A and 13B show the state before the semiconductor devices are separated. In particular, FIG. 13A shows the boundary of the resin 8 with a dot chain line 20 in a state where the resin 8 has been seen through. However, due to the resin pressure at the time of resin injection, the lead wire 4 and the die holder 2 are easily raised. Therefore, for example, if the resin 8 is extended under the lead 4 and the bottom of the lead 4 is covered with resin, the semiconductor device cannot be electrically connected to the mother substrate. 200402128 In order to solve the aforesaid disadvantages, as shown in Figs. 14A and 14B, there has been a method of sealing the resin by attaching a film 9 under the lead frame 1 to integrate them. However, in the conventional resin sealing method, only the area 9a shown by hatching in Fig. 14A can be clamped by the upper and lower molds. Therefore, the area 9b of the film 9 shown by the wavy line 5 in FIG. 14B, that is, not only the inner edge portion below the outermost lead 4 but also the entire underside of the die seat 2 is not completely adhered to the film 9 . As a result, the injected resin 8 expands and coats under the lead 4 or under the die pad 2, the resin remains in an expanded state and solidifies, which may cause unevenness under the final product. Therefore, there has been another method of sealing electronic parts with 10 resins (for example, refer to Patent Document 1). Patent Document 1 International Publication No. 00/66340, that is, a lead frame that overlaps with an adhesive film to have a flat surface A method for resin sealing after clamping the lower clamp body and the upper clamp body with a grid-shaped pressing protrusion and sticking them together. Problems to be Solved by the Invention However, in the aforementioned film bonding method, the lead frame, the upper and lower clamps, and the film have non-uniformity in thickness and surface accuracy. Therefore, in the case where it has been combined, due to the cumulative error, the pressure load on the upper and lower clamps is not uniform. As a result, the film cannot be uniformly adhered to the underside of the lead frame, and the resin cannot be completely prevented from entering the gap between the film and the lead frame when the resin is sealed. [^^ 明 内 j Summary of the invention In view of the foregoing shortcomings, the present invention aims to provide a film sticking device and a film 200402128 sticking method. The film sticking device can completely prevent the expansion of the resin during resin sealing and can The film is uniformly adhered under the semiconductor device and integrated. Means for Solving the Problem 5 In order to achieve the above-mentioned object, the film bonding device of the present invention is capable of freely peeling a film under a substrate that has been connected by a wire to a semiconductor wafer mounted on a die holder and a lead, The film attachment device is composed of an upper clip body and a lower clip body. The upper clip system has a recess below that does not interfere with the semiconductor wafer and the wires, and the lower clip body is provided with the 10 films. The mounting surface is provided with a vent hole, and the outer peripheral portion of the substrate is clamped by the lower clamp body and the upper clamp body, and the gas return from the vent hole can be switched from negative pressure to positive pressure. In addition, the substrate includes not only a lead frame made of a metal monomer, but also a resin substrate made of a resin material, for example, a high-definition organic package substrate. According to the present invention, by switching the gas return flow from the vent holes in the lower clamp body from a negative pressure to a positive pressure, the film can be pressed on the substrate with air pressure without damaging the semiconductor wafer and the wires. . Therefore, the aforementioned film systems are uniformly adhered to the substrate and are integrated with each other. As a result, even if sealed with a resin, the resin does not spread under the substrate, and a good semiconductor device can be obtained. A vent hole communicating with the recess of the upper clamp body may also be provided. According to this embodiment, the gas is exhausted through the ventilation holes. Therefore, even if the gas return flow of the ventilation holes is switched from negative pressure to positive pressure, no gas will remain between the film and the substrate. It is firmly integrated. In the recess of the upper body, a position restricting protrusion for restricting excessive floating of the substrate may be provided prominently. According to this embodiment, the semiconductor substrate or the substrate can be prevented from being damaged by preventing the substrate from floating excessively. In the recess of the upper clamp body, a plurality of partitioning die seats may be protrudingly provided, and the clamping protrusions for clamping the substrate together with the lower clamp body. According to this embodiment, the clamping protrusions reduce the floating of the substrate, so that the film and the substrate are more surely adhered. ο The vent holes located on the lower side of the aforementioned die seat may be discontinuous from the vent holes located on the lower side of the die seat. According to this embodiment, the above-mentioned vent holes located on the lower side of the die seat and the vent holes located on the side other than the lower side of the die seat can switch the gas backflow from negative pressure to positive pressure at different points in time. 15 Clamp-shaped mounting surfaces on which the enemy is placed may be formed with flail vents, and the ventilation grooves are located on the lower side of the lead. According to this embodiment, if the gas return flow of the vent hole is switched from negative pressure to positive pressure, the film located at the portion where the vent groove is formed can be reliably adhered to the lead frame. Therefore, it is possible to prevent the resin from spreading toward the back side of the ^ 20 frame when the resin is sealed, and it is possible to surely prevent poor contact. In particular, on the mounting surface on which the body which is lost under the aforementioned film is placed, there may be formed a ventilation groove connected to most of the ventilation grooves' and located below the free end of the lead before cutting. According to this embodiment, by switching the gas return flow of the vent hole from negative soil 200402128 to positive pressure, the film can be reliably adhered to the free end edge of the lead wire before cutting. Therefore, the resin can be prevented from spreading toward the inner surface of the lead during the resin sealing, and contact failure can be prevented more reliably. The film may have a peeling tongue having a shape protruding from the outer peripheral edge portion 5 of the substrate at at least one edge portion. According to this embodiment, the film peeling operation after resin sealing is simpler, more convenient, and can be easily automated. The film attaching method of the present invention is a method in which a film can be freely peeled on a substrate which has been connected by a wire to a semiconductor wafer mounted on a die holder and a lead substrate, and the film is placed in a lower clamp. The mounting surface of the body is formed with a vent hole, and then the substrate is superposed on the film, and the peripheral edge of the substrate is clamped by the upper body and the lower clamp body which have recesses that do not interfere with semiconductor wafers and wires. After the treatment, the step of causing gas to be discharged from the vent hole is performed. 15 Another method for attaching a film according to the present invention is a method for attaching a film which can be freely peeled to a substrate which has been connected by a wire to a semiconductor wafer mounted on a die holder and a lead.

Then, after the gas return of the central vent hole 22 is switched from negative pressure to positive pressure, the gas return of the crotch vent hole 23 is switched from negative pressure to positive pressure. Therefore, after a part of the film 30 located at the center of the lower surface of the die pad 32 is adhered, the film 30 is sequentially adhered and adhered to the bottom of the tie rod 31a and the lead 34. The film 30 is attached from the center of the lower surface of the die holder 32 to the outside, so that the air remaining between the film 30 and the lead frame 31 is pressed out. Moreover, the extruded air is exhausted to the outside through the ventilation hole 25b of the upper clamp body 25. 20 And 'If the gas is expelled from the central vent hole 22 and the crotch vent hole 23 of the lower clip 21 mentioned above, the tight film 30 and the lead frame 31 are pressed upward, and the film 30 and the lead frame 31 are more firmly attached to the whole. Into. However, when the lead frame 31 floats only a predetermined amount, the position restricting protrusion 28 abuts a portion of the lead frame 31 between the package and the package to restrict the position of the lead frame 31 to prevent plastic deformation of the lead frame 12 200402128 31 . The adhesion of the film is not limited to the foregoing embodiment. For example, the ventilation hole 25b of the upper clip 25 can be used to absorb and reduce the pressure, so that the film 30 and the lead frame 31 can be attracted and adhered to each other. — Body. 5. Another method for attaching the film 30 is to feed the film 30 to the lower holder 21 and place the lead frame 31 thereon to determine the position. Next, the lower body 21 is heated to increase the adhesive force of the film 30, and then the film 30 and the lead frame 31 are attracted to each other and integrated together. The aforementioned lead frame 31 having the film 30 integrated thereon is transported to the lead frame transfer unit 41 of the resin sealing device 40 through the pick-up and pressing unit 16 as shown in FIG. 10. The lead frame 31 transferred to the lead frame transfer unit 41 is transferred to the preheating unit 43 through the internal loader 42 and is heated for a predetermined time. And, the inner loader 42 receives the heated 45 (solid resin material) from the heated lead frame 31 and the ingot carrier 44 and transfers it to the lower die 47 which has been installed under the pressure 15 unit 46. Further, the lead frame 31 and the ingot 45 are placed at predetermined positions of the lower die 47.
