Abstract

PURPOSE:To conduct an excellent sealing of the package of the semiconductors by heating two planar molded members having recess for containing a semiconductor by mating in integrating molds, then interposing a lead frame therebetween, pressing to mate them and thereby preventing the production of flash. CONSTITUTION:The lead frame 4 is interposed between the integrating molds 9 and 9', the planar molded member 3 is disposed in the recess 17 of the integrating molds 9 in the state that the mating surfaces 16 of the member 3 are brought into contact with the lead frame 4, a heater guide hole 19 passed through the recess 17' of the molds 9' is perforated on one side of the mold 9' in the state that the part 18 making contact with the lead frame is retained on the one side surface of the mold 9', the heater 20 is inserted from the hole 19, the planar molded momber 3' is so disposed as not to contact therewith, heated, and the heater 20 is removed, and then the members are confronted integrally and heated by planar molde member pressing machines 12, 12'. Since the peripheries of the planar molded members are completely closed in this manner, it can prevent the production of flash.
