Patent ID: 11088269

Abstract:
According to one embodiment, a semiconductor device includes a first electrode, a second electrode, a third electrode, a first nitride region, a second nitride region, and a first insulating film. The first nitride region includes Alx1Ga1-x1N. The first nitride region includes first and second partial regions, a third partial region between the first and second partial regions, a fourth partial region between the first and third partial regions, and a fifth partial region between the third and second partial regions. The second nitride region includes Alx2Ga1-x2N. The second nitride region includes sixth and seventh partial regions. The first insulating film includes a first insulating region and is between the third partial region and the third electrode. The third partial region has a first surface opposing the first insulating region. The fourth partial region has a second surface opposing the sixth partial region.
