Abstract:
A semiconductor device including: a semiconductor substrate; a drift region of first conductivity type that is formed in the semiconductor substrate; an accumulation region of first conductivity type that is formed above the drift region and has higher concentration than concentration of the drift region; a base region of second conductivity type that is formed above the accumulation region; and a gate trench portion that is formed extending from an upper surface of the semiconductor substrate to the drift region, passing through the base region and the accumulation region, wherein a maximum value of doping concentration of the accumulation region is greater than a maximum value of doping concentration of the base region will be provided.

Claim (Index 10):
The semiconductor device according to  claim 1 , further comprising\n a dummy trench portion that is formed extending from an upper surface of the semiconductor substrate to the drift region, passing through the base region and the accumulation region, wherein doping concentration of a part, in the accumulation region, adjacent to the dummy trench portion is higher than doping concentration of a part adjacent to the gate trench portion.
