摘要： According to an example embodiment, a method includes forming a nitrogen vacancy surface layer by treating a surface of an n-type nitride semiconductor with inert gas plasma, and forming an oxygen-added nitride film by treating a surface of the nitrogen vacancy surface layer with oxygen-containing gas plasma, and forming an electrode on the oxygen-added nitride film. The nitrogen vacancy surface layer lacks a nitrogen element.
