Abstract
A semiconductor device of an embodiment includes first and second electrodes, a first gate electrode, a semiconductor layer disposed between the first electrode and a band gap of the semiconductor layer being wider than a band gap of silicon, a silicon layer between the semiconductor layer and the first electrode, a metal layer between the semiconductor layer and the silicon layer, a first semiconductor region of a first-conductivity type in the semiconductor layer, a first silicon region of the first-conductivity type in the silicon layer, a second silicon region of a second-conductivity type in the first silicon region, a third silicon region of the second-conductivity type in the first silicon region and separated from the second silicon region, a first gate insulating layer, a fourth silicon region of the first-conductivity type in the second silicon region, and a fifth silicon region in the third silicon region.
