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 9):
The semiconductor device according to  claim 5 , wherein\n the source region and the channel region are adjacently formed in a direction along the upper surface of the silicon carbide layer, and the gate insulating film is formed on the upper surface of the silicon carbide layer.
