ABSTRACT:
Part of a first oxide film formed by thermal oxidation is removed by etching. A second oxide film is formed in the part of substrate from which the first oxide film has been removed using heated nitric acid. The two oxide films are nitrided by a nitrogen plasma having a low energy so as to be first and second gate insulating films, i.e., oxynitride films, respectively.
