Abstract:
1. A method for manufacturing a group III nitride compound semiconductor device, comprising: forming a resist layer on a group III nitride compound semiconductor in a wafer; patterning said resist layer; and irradiating a surface of said wafer with ultraviolet rays to thereby clean a resist residue from said surface of said wafer, said surface comprising said group III nitride compound semiconductor, wherein said ultraviolet rays cause a reaction of oxygen molecules to form stimulated oxygen atoms having a strong oxidative power at said surface of said wafer, and wherein said irradiating said surface of said wafer is performed in a gaseous environment and after said patterning said resist layer, wherein said irradiating said surface of said wafer comprises irradiating a surface of said group III nitride compound semiconductor.
