Abstract
A semiconductor device of an embodiment includes a semiconductor layer, a first insulating film provided on the semiconductor layer, a first electrode film provided on the first insulating film, a second electrode film provided on the first electrode film, and a first field plate electrode provided on the second electrode film. A lower end of the first field plate electrode is located on a second surface of the first electrode film, the second surface being in contact with the second electrode film, rather than a first surface of the first electrode film, the first surface being in contact with the first insulating film.
