Abstract:
A semiconductor device includes a semiconductor layer made of a wide bandgap semiconductor and including a gate trench; a gate insulating film formed on the gate trench; and a gate electrode embedded in the gate trench to be opposed to the semiconductor layer through the gate insulating film. The semiconductor layer includes a first conductivity type source region; a second conductivity type body region; a first conductivity type drift region; a second conductivity type first breakdown voltage holding region; a source trench passing through the first conductivity type source region and the second conductivity type body region from the front surface and reaching a drain region; and a second conductivity type second breakdown voltage region selectively formed on an edge portion of the source trench where the sidewall and the bottom wall thereof intersect with each other in a parallel region of the source trench.

Claim (Index 3):
The semiconductor device according to  claim 2 , further comprising an SiC substrate having a first surface and a second surface facing the opposite side of the first surface of the SiC substrate, wherein\n the SiC substrate is disposed on the second surface side of the first semiconductor layer such that the second surface of the first semiconductor layer faces the first surface of the SiC substrate, and the third conductive layer is formed on a second surface side of the SiC substrate.
