Abstract:
1. A method of manufacturing a semiconductor device including forming a silicide layer on a surface of a semiconductor layer, the method comprising: forming in the semiconductor layer a p-type impurity region, an n-type impurity region and a (p+n)-type impurity region between the n-type and p-type impurity regions by implanting impurities; after formation of the p-type impurity region, the n-type impurity region and the (p+n)-type impurity region, heat treating the semiconductor layer at the temperature of 1000° C. or more; after the heat treatment, removing a part of a surface region of the semiconductor layer; after removing the part of the surface region, forming a metallic material film on the semiconductor layer; and after formation of the metallic material film, forming a silicide layer by heat treating the metallic material film.
