Patent ID: 8829535

Claim:
A silicon carbide semiconductor device comprising: an insulation film, and a silicon carbide layer having a surface covered with said insulation film, said surface including a first region, said first region having a first plane orientation at least partially, said first plane orientation being any of a (0-33-8) plane, (30-3-8) plane, (-330-8) plane, (03-3-8) plane, (−303-8) plane, and (3-30-8) plane, wherein said surface of said silicon carbide layer further includes a second region, said second region having a second plane orientation differing from said first plane orientation, at least partially, said second plane orientation is any of the (0-33-8) plane, (30-3-8) plane, (-330-8) plane, (03-3-8) plane, (-303-8) plane, and (3-30-8) plane.
