Abstract
A semiconductor device is formed by 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 the compound film &agr;&ggr;x to reduce the base layer and thereby oxidizing the compound film &agr;&ggr;x on an interface of the compound film &agr;&ggr;x and the base layer, wherein each of x and y is a ratio of the number of atoms of the element &ggr; to the number of atoms of the element &agr;, and z is a ratio of the number of atoms of the oxygen to the number of atoms of the element &agr;.
