Abstract

A semiconductor device includes a semiconductor layer which has a first device formation region and a second device formation region, a first HEMT which is formed in the first device formation region and has a first two-dimensional electron gas region as a channel, a second HEMT which is formed in the second device formation region and has a second two-dimensional electron gas region as a channel, and a region separation structure which is formed in the semiconductor layer and defines the first device formation region and the second device formation region.
