Abstract:
A method of manufacturing a semiconductor device wherein a sealing resin is dropped from a nozzle and is admitted between a semiconductor chip and a wiring substrate, said method comprising the steps of:providing said wiring substrate having: a recess; a stepped portion; and a resin passage, said stepped portion being formed in part of said recess and having a first face higher than a bottom of the recess, said resin passage being adjacent to said stepped portion and contiguous to the bottom of said recess; providing said semiconductor chip having salient electrodes; flip-chip-connecting said semiconductor chip to the recess of said wiring substrate; disposing said nozzle so as to partially overhang a corner portion of the first face of said stepped portion; and dropping the resin from said nozzle onto the corner portion of said stepped portion, allowing the resin to be admitted between the bottom of said wiring substrate and said semiconductor chip through said resin passage.
