Abstract:
1. A semiconductor device that comprises a semiconductor chip and has a current flow in a thickness direction of the semiconductor chip, the semiconductor device comprising: an active section comprising a base region of a second conductivity type formed selectively on a first major surface side of the semiconductor chip, a semiconductor substrate layer of a first conductivity type, of which a first major surface side is on a second major surface side of the semiconductor chip, and a drift layer between the semiconductor substrate layer and the base region; a first main electrode connected electrically to the base region; a pillar region of a first conductivity type formed along a scribe plane of the semiconductor chip; an edge terminating section surrounding the active section and on the first major surface side of the semiconductor substrate layer, the edge terminating section consisting essentially of a first semiconductor region of the second conductivity type formed between the active section and the pillar region; and a second main electrode connected electrically to a second major surface side of the semiconductor substrate layer.
