Abstract:
1. A semiconductor device, comprising: a substrate; a transistor that comprises a first electron transit layer and an electron supply layer which are stacked in a thickness direction of the substrate; a second electron transit layer formed over the substrate in parallel to the first electron transit layer and the electron supply layer; an insulating layer that insulates the transistor and the second electron transit layer from each other, the insulating layer being between the first electron transit layer and the second electron transit layer in the thickness direction of the substrate; an anode electrode that forms a Schottky junction with the second electron transit layer; and a cathode electrode that forms an ohmic junction with the second electron transit layer, wherein the anode electrode is connected to a source of the transistor, and the cathode electrode is connected to a drain of the transistor.
