Abstract:
A semiconductor device includes a semiconductor layer of a first conductivity type. A well region that is a second conductivity type well region is formed on a surface layer portion of the semiconductor layer and has a channel region defined therein. A source region that is a first conductivity type source region is formed on a surface layer portion of the well region. A gate insulating film is formed on the semiconductor layer and has a multilayer structure. A gate electrode is opposed to the channel region of the well region where a channel is formed through the gate insulating film.

Claim (Index 10):
The semiconductor device according to  claim 5 , wherein\n the source region and the channel region are adjacently formed in a direction orthogonal to the upper surface of the silicon carbide layer, a trench dug down from the upper surface of the source region to pass through the source region and the well region is formed in the silicon carbide layer, and the gate insulating film is formed on the inner surface of the trench.
