Abstract:
A method of manufacturing a semiconductor device comprising the steps of:(a) providing a plurality of semiconductor chips and a wiring substrate, each of said semiconductor chips having a plurality of electrodes formed on a main surface thereof, said wiring substrate having a main surface, a plurality of electrodes formed thereon and a rear surface opposing said main surface, said wiring substrate being comparted by a compartment line to provide a plurality of chip mounting areas; (b) mounting said plurality of semiconductor chips on said plurality of chip mounting areas of said wiring substrate respectively; (c) electrically connecting said plurality of electrodes of said semiconductor chips with said plurality of electrodes of said wiring substrate in each of said plurality of chip mounting areas; (d) sealing said main surface of said wiring substrate and said plurality of semiconductor chips with a resin member by a transfer molding method using a molding die having a first die and a second die that are disposed on said main surface of said wiring substrate to have a predetermined space between cavities defined by said first and second dies; and (e) after the step (d), dividing said wiring substrate and said resin member along said compartment line, to provide a plurality of semiconductor packages each having said semiconductor chip sealed by a part of said resin member, wherein the step (d) is performed such that said plurality of semiconductor chips are sealed by said resin member injected in said cavities of each of said first and second dies of said molding die to provide a first group of semiconductor chips sealed by a first resin block and a second group of semiconductor chips sealed by a second resin block, and wherein the step (e) includes a step of dividing both said first and second resin blocks, thereby to provide said plurality of semiconductor packages including said first and second groups of semiconductor chips respectively.
