Abstract

A method for manufacturing a Group III nitride semiconductor of the present invention, comprising a sputtering step for disposing a substrate and a target in a chamber and forming a Mg-doped Group III nitride semiconductor on the substrate by a reactive sputtering method, wherein the sputtering step includes respective substeps of: a film formation step for forming a semiconductor thin film while doping with Mg; and a plasma treatment step for applying an inert gas plasma treatment to the semiconductor thin film that has been formed in the film formation step, and the Group III nitride semiconductor is formed by laminating the semiconductor thin film through alternate repetitions of the film formation step and the plasma treatment step.
