Abstract:
1. A vertical semiconductor device including a GaN-based stacked layer having an opening, the semiconductor device comprising: a regrown layer including a channel located so as to cover a wall surface of the opening; a p-type GaN-based semiconductor layer having an end face covered with the regrown layer at the wall surface of the opening; an n a p a gate electrode located on the regrown layer in the opening; and a source electrode located on the GaN-based stacked layer around the opening so as to be in contact with the regrown layer and the n wherein the regrown layer includes an electron drift layer and an electron source layer and the channel is formed of two-dimensional electron gas generated in the electron drift layer at a position near an interface between the electron drift layer and the electron source layer, and the p the n
