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 15):
The semiconductor device according to  claim 1 , wherein\n the gate trench portion has:\n a trench 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; \n an insulating film that is formed on an inner wall of the trench; \n a gate conductive portion that is formed, in the trench, facing the base region; and \n a dummy conductive portion that is formed below the gate conductive portion and insulated from the gate conductive portion, and \n at least partial region of the accumulation region is formed facing the dummy conductive portion.
