Abstract

A method for manufacturing a semiconductor device includes: sequentially depositing a gate insulating filmcomposed of a high dielectric constant film containing one or more metallic element(s) selected from a group consisting of Hf, Zr, Al, La and Ta, a barrier filmcomposed of one or more metal nitride selected from a group consisting of TiN, TaN and WN, a metallic filmand a polycrystalline silicon filmon the semiconductor substrate (p-type semiconductor substrate) to form a multiple-layered film; and silicidizing a lower portion of the polycrystalline silicon filmto form a lower layer (forming a first silicide layer) by conducting a heat treatment of the multiple-layered film to diffuse the metal of the metallic filminto the polycrystalline silicon film
