Abstract

A method for producing a semiconductor device, includes forming a first carrier transport layer including a Group III nitride semiconductor, forming a mask on a region of the first carrier transport layer, selectively re-growing a second carrier transport layer on an unmasked region of the first carrier transport layer, the second carrier transport layer including a Group III nitride semiconductor, and selectively growing a carrier supply layer on the second carrier transport layer, the carrier supply layer including a Group III nitride semiconductor having a bandgap different from that of the Group III nitride semiconductor of the second carrier transport layer.
