Patent ID: 8735908

Claim:
A semiconductor device comprising: a substrate including silicon; a first silicon carbide film disposed on a surface of the silicon; a mask member disposed on a surface of the first silicon carbide film; and a second silicon carbide film that covers the first silicon carbide film in an opening section of the mask member, a semiconductor element including a source region, a drain region and a body contact region, the body contact region disposed adjacent to the source region, the body contact region having an opposite conductivity as a conductivity of the source region, at least a part of the second silicon carbide film including the body contact region, and the body contact region including an coalesced defect of the second silicon carbide film, the coalesced defect being disposed in a portion of the second silicon carbide film directly below the body contact region, the second silicon carbide region including defect free regions on both sides of the coalesced defect.
