Abstract:
1. A method for manufacturing a semiconductor device comprising steps of: pasting to a support body a plurality of base plates as heat sinks on which respective semiconductor chips are mounted, at a predetermined interval; forming a sealing resin in the support body such that the sealing resin covers the plurality of base plates and a plurality of the semiconductor chips; forming wiring patterns in the sealing resin such that the wiring patterns are electrically connected to the respective semiconductor chips; forming a wiring protective film in the sealing resin including the wiring patterns such that part of the wiring patterns are exposed; forming external electrodes such that the external electrodes contact the wiring patterns exposed from the wiring protective film; individually dividing the plurality of the semiconductor chips integrated by the sealing resin by cutting the sealing resin and the wiring protective film; and peeling off from the support body the plurality of semiconductor chips and the base plates covered by the sealing resin, after individually dividing the plurality of the semiconductor chips.
