    摘要: Provided is a semiconductor device containing a silicon single crystal substrate 101, a silicon carbide layer 102 provided on a surface of the substrate, a Group III nitride semiconductor junction layer 103 provided in contact with the silicon carbide layer, and a superlattice-structured layer 104 constituted by Group III nitride semiconductors on the Group III nitride semiconductor junction layer. In this semiconductor device, the silicon carbide layer is a layer of a cubic system whose lattice constant exceeds 0.436 nm and is not more than 0.460 nm and which has a nonstoichiometric composition containing silicon abundantly in terms of composition, and the Group III nitride semiconductor junction layer has a composition of AlxGayInzN1-αMα (0≦X, Y, Z≦1, X+Y+Z=1, 0≦α
