Assignee: KABUSHIKI KAISHA TOSHIBA
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a silicon carbide member,
the silicon carbide member including
an operating region including at least one of a diode or a transistor, and
a first element region including at least one element selected from the group consisting of Ar, V, Al and B,

the first element region including a first region and a second region, a first direction from the first region toward the second region being along a [1-100] direction of the silicon carbide member, the operating region being between the first region and the second region in the first direction, and a second direction being along a [11-201 of the silicon carbide member,
the first element region not including a region overlapping the operating region in the second direction, or the first element region including a third region overlapping the operating region in the second direction, a first length of the first region along the first direction being longer than a third length of the third region along the second direction, a second length of the second region along the first direction being longer than the third length.
