Abstract

See full text

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.
