Patent ID: 11658235

Abstract:
According to one embodiment, a semiconductor device includes a first electrode, a first region, and a first insulating layer. The first electrode includes a first electrode portion. The first region contains Ga and N. The first region includes a first subregion, a second subregion, and a third subregion. The first subregion and the third subregion contain at least one first element selected from the group consisting of Ar, B, P, N, and Fe. The first subregion is located between the first electrode portion and the second subregion in a first direction. The second subregion does not contain the first element, or concentration of the first element in the second subregion is lower than concentration of the first element in the first subregion and lower than concentration of the first element in the third subregion. The first insulating layer is provided between the first electrode and the first region.
