Abstract:
A semiconductor device of the present invention includes a gate electrode buried in a gate trench of a first conductivity-type semiconductor layer, a first conductivity-type source region, a second conductivity-type channel region, and a first conductivity-type drain region formed in the semiconductor layer, a second trench selectively formed in a source portion defined in a manner containing the source region in the surface of the semiconductor layer, a trench buried portion buried in the second trench, a second conductivity-type channel contact region selectively disposed at a position higher than that of a bottom portion of the second trench in the source portion, and electrically connected with the channel region, and a surface metal layer disposed on the source portion, and electrically connected to the source region and the channel contact region.

Claim (Index 31):
The semiconductor device according to  claim 30 , further comprising:\n a channel contact region of a second conductivity type selectively disposed on a surface side relative to the semiconductor layer, such that the channel contact region is electrically connected with the channel region; and a surface metal layer electrically connected with the source region and the channel contact region.
