Abstract:
On a front surface of a semiconductor base, an n − -type drift layer, a p-type base layer, an n ++ -type source region, and a gate trench and a contact trench penetrating the n ++ -type source region and the p-type base layer and reaching the n − -type drift layer are provided. The contact trench is provided separated from the gate trench. A Schottky metal is embedded in the contact trench and forms a Schottky contact with the n − -type drift layer at a side wall of the contact trench. An ohmic metal is provided at a bottom of the contact trench and forms an ohmic contact with the n − -type drift layer.

Claim (Index 4):
The semiconductor device according to  claim 1  further comprising\n a second metal electrode forming an ohmic contact with the first semiconductor layer at a bottom of the second trench.
