Abstract:
The semiconductor device includes: a semiconductor layer in which a trench is formed having a side surface and a bottom surface; a second conductivity-type layer formed on the semiconductor layer on the side surface and the bottom surface of the trench; a first conductivity-type layer formed on the semiconductor layer so as to contact the second conductivity-type layer; a first electrode electrically connected to the first conductivity-type layer; a second electrode embedded in the trench and electrically connected to the second conductivity-type layer; and a barrier-forming layer which is arranged between the second electrode and the side surface of the trench and which, between said barrier-forming layer and the second conductivity-type layer, forms a potential barrier higher than the potential barrier between the second conductivity-type layer and the second electrode.

Claim (Index 31):
The semiconductor device according to  claim 28 , further comprising a second conductivity type source breakdown voltage holding layer that is formed so as to be continuous with the channel layer and that is disposed on the side surface and the bottom surface of the source trench.
