In a semiconductor module, second semiconductor chips (e.g., diodes) are disposed closer to a laminated substrate than first semiconductor chips (MOSFETs). When a control signal supplied to gate electrodes of the first semiconductor chips (MOSFETs) is off, an electric current produced by a voltage from source terminals to a drain board mainly flows through the second semiconductor chips.

Semiconductor module

A method of manufacturing a semiconductor device and a semiconductor device that is manufactured by the method. In the method of manufacturing a semiconductor device, a releasing sheet is disposed in close contact with a hole of an aluminum plate having the recessed hole, and a skeleton structure of a semiconductor device is put into the recessed hole. Then, liquid epoxy resin is poured into the recessed hole. After hardening, the epoxy resin bodyincluding the skeleton structure is taken out from the recessed hole to complete manufacturing the semiconductor device. Using a simple molding jig including the aluminum plate, and covering the skeleton structure with the epoxy resin body, a highly reliable semiconductor device with a case-less construction can be manufactured.
