| Zusammenfassung: | A semiconductor device includes a semiconductor body, a first electrode on a back surface of the semiconductor body, second and third electrodes provided on a front surface of the semiconductor body, a first film linking the second electrode and the third electrode, and a second film between the semiconductor body and the first film. The first film has a higher resistivity than the first semiconductor body, and the second film is insulative. The second film includes a first-film-thickness portion and a second-film-thickness portion. The first-film-thickness portion has a first film thickness along a first direction directed from the first electrode toward the second electrode. The second-film-thickness portion has a second film thickness along the first direction thicker than the first film thickness. The first-film-thickness portion and the second-film-thickness portion surround the second electrode. The first film extends along surfaces of the first-film-thickness portion and the second-film-thickness portion. |
