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 13):
The semiconductor device according to  claim 1 , wherein\n the accumulation region is formed in a region sandwiched by two of the gate trench portions that are lined up in a lateral direction; and a length of the accumulation region in a depth direction is smaller than an interval in a lateral direction between central portions of two of the gate trench portions.
