Abstract:
1. A semiconductor device comprising: a semiconductor substrate of first conductivity type having a first face and a second face; a first electrode provided on a side of the first face; a first semiconductor layer of second conductivity type provided on a side of the second face of the semiconductor substrate; a second semiconductor layer of first conductivity type selectively provided on the first semiconductor layer in a first region of the second face; an insulating film provided on the second face; a gate extraction pad provided above the insulating film in a second region of the second face, the second region being next to the first region; a gate electrode provided on the first semiconductor layer and the second semiconductor layer via the insulating film in the first region, the gate electrode being positioned between the semiconductor substrate and the gate extraction pad in the second region, the insulating film being provided between the semiconductor substrate and the gate electrode; and a second electrode electrically connected to the first semiconductor layer and the second semiconductor layer in the first region.
