Abstract:
A wide band gap semiconductor device includes a semiconductor layer, a trench formed in the semiconductor layer, first, second, and third regions having particular conductivity types and defining sides of the trench, and a first electrode embedded inside an insulating film in the trench. The second region integrally includes a first portion arranged closer to a first surface of the semiconductor layer than to a bottom surface of the trench, and a second portion projecting from the first portion toward a second surface of the semiconductor layer to a depth below a bottom surface of the trench. The second portion of the second region defines a boundary surface with the third region, the boundary region being at an incline with respect to the first surface of the semiconductor layer.

Claim (Index 2):
The semiconductor device according to  claim 1 , further comprising a surrounded portion at least partially surrounded by the semiconductor layer, a bottom of the surrounded portion being between the first surface of the semiconductor layer and the second surface of the semiconductor layer, the surrounded portion being disposed immediately above the first portion of the second region.
