Abstract

A semiconductor device includes a third first-conductivity-type semiconductor layer on a semiconductor substrate, and a first pillar-shaped semiconductor layer on the semiconductor substrate. The first pillar-shaped semiconductor layer including a first first-conductivity-type semiconductor layer, a first body region, a second first-conductivity-type semiconductor layer, a first second-conductivity-type semiconductor layer, a second body region, a second second-conductivity-type semiconductor layer, and a third second-conductivity-type semiconductor layer. A first gate insulating film is around the first body region, and a first gate is around the first gate insulating film. A second gate insulating film is around the second body region and a second gate is around the second gate insulating film. An output terminal is connected to the second first-conductivity-type semiconductor layer and the first second-conductivity-type semiconductor layer, and a first contact connects the first gate and the second gate.
