Patent ID: 6919223

Claim:
A method of manufacturing a semiconductor resin molding comprising steps of: preparing a mold having an upper mold section and a lower mold section; preparing a semiconductor chip mounted substrate formed by mounting a semiconductor chip on a substrate through a connecting electrode; fitting said semiconductor chip mounted substrate into a cavity (concave portion for setting) of said lower mold section; injecting underfill resin into a first clearance between said semiconductor chip and said substrate; setting a resin member, having an initial thickness larger than the height of a second clearance that will be defined between the top surface of a cavity of said upper mold section and the upper surface of said semiconductor chip when said upper mold section and said lower mold section are closed, on the upper surface of said semiconductor chip; and molding said underfill resin while applying pressure from said upper mold section to said resin member by closing said upper mold section and said lower mold section.
