Abstract:
A method for producing a semiconductor power device includes forming a gate trench from a surface of the semiconductor layer toward an inside thereof. A first insulation film is formed on the inner surface of the gate trench. The method also includes removing a part on a bottom surface of the gate trench in the first insulation film. A second insulation film having a dielectric constant higher than SiO2 is formed in such a way as to cover the bottom surface of the gate trench exposed by removing the first insulation film.

Claim (Index 17):
The semiconductor device according to  claim 11 , wherein the first source region and the first body region are formed at a first side direction of the gate trench, and a diode region is formed at a second side direction of the gate trench, so that an asymmetrical portion formed so as to be asymmetrical with respect to the gate trench is included in the semiconductor device.
