| Zusammenfassung: | A semiconductor device includes: a first conductivity type semiconductor layer having a main surface and including a device region; a second conductivity-type base region formed in a surface layer portion of the main surface in the device region; a first-conductivity-type source region which defines a channel region between the semiconductor layer and the first-conductivity-type source region, and which is formed in a surface layer portion of the base region so as to be spaced inward from an edge portion of the base region; a second conductivity type base contact region formed in a surface layer portion of the base region; a first conductivity-type well region that defines a drift region between the base region and the first conductivity-type well region, the first conductivity-type well region being formed in a surface layer portion of the main surface at a distance from the base region in the device region; a first conductivity-type drain region formed in a surface layer portion of the well region; a second |
