After a silicon oxide film, which is a main component of a first potential barrier film, is formed with a plasma oxidation method, plasma nitridation at a high temperature and a heat treatment in an atmosphere containing nitric oxide are performed in combination, thereby forming a silicon oxynitride film on the surface of the silicon oxide film, and segregating nitrogen to an interface between the silicon oxide film and a semiconductor substrate.
