Patent ID: 6929977

Claim:
A method for simultaneously molding a plurality of semiconductor chips, comprising the following steps: a) securing said plurality of semiconductor chips with a first chip surface to a substrate so that spaces are provided between neighboring semiconductor chips on said substrate; b) inserting said substrate with said semiconductor chip. thereon into a mold portion ( 2 ); c) covering a second chip surface facing opposite said first chip surface of said plurality of semiconductor chips with a mold release film; d) simultaneously and individually applying equal pressure to all of said second chip surfaces of said plurality of semiconductor chips so that each said second chip surface is fully covered by said mold release film, and so that gaps between said second chip surfaces and said mold release film are avoided; e) closing said mold portion, except for a resin feed-in gate ( 19 ), to form a mold cavity between said mold release film and said substrate, whereby said plurality of semiconductor chips is enclosed in said mold cavity; f) filling said mold cavity between said substrate and said mold release film with resin; g) letting said resin set to form a molding ( 38 ) with said plurality of semiconductor chips held in place on said substrate by said resin; and h) opening said mold and removing said molding ( 38 ) from said mold portion.
