    摘要: A semiconductor device has a single unit capable of improving adhesion to a cooling body and a heat dissipation performance, and an aggregate of the single units is capable of configuring any circuit at a low cost. A single unit (101) includes copper blocks (1, 8), an insulating substrate (6) with a conductive pattern, an IGBT chip (10), a diode chip (13), a collector terminal pin (15), implant pins (17) fixed to the chips (10) by solder (11), a printed circuit board (16) having the implant pins (17) fixed thereto, an emitter terminal pin (19), a control terminal pin (20), a collector terminal pin (15), and a resin case (21) having the above-mentioned components sealed therein. The copper blocks (1, 8) make it possible to improve adhesion to a cooling body and the heat dissipation performance. A plurality of single units (101) can be combined with an inter-unit wiring board to form any circuit.
