Abstract:
A method of manufacturing a semiconductor device comprising:a compound film &agr;&ggr;x made of at least one element &agr; selected from metal elements and at least one element &ggr; selected from the group consisting of boron, carbon, and nitrogen on a base layer containing oxygen (O); and forming a compound film &agr;&ggr;yOz by causing said compound film &agr;&ggr;x to reduce said base layer and thereby oxidizing said compound film &agr;&ggr;x on an interface of said first compound film &agr;&ggr;x and said base layer, wherein each of x and y is a ratio of the number of atoms of said element &ggr; relative to the number of atoms of said element &agr;, &ggr; being greater than zero, and z is a ratio of the number of atoms of said oxygen relative to the number of atoms of said element &agr;.
