Abstract:
1. A semiconductor device comprising: a plurality of body regions having a source or an emitter region that is made of an SiC semiconductor, and a drain or a collector region that is made of an SiC semiconductor; a well region that is annular when viewed planarly and surrounds the plurality of body regions; a channel region that is made of an SiC semiconductor and that is disposed between the source or the emitter region and the drain or the collector region; a gate that faces the channel region with a gate insulating film disposed between the gate and the channel region; and a diode formed such that a part thereof faces a region between the well region and a region of the plurality of body regions nearest the well region, with the gate insulating film disposed therebetween; wherein the diode is made of the same material as that of the gate and is connected between the gate and the source or the emitter region.
