    Abstract: A first tungsten silicide layer relatively rich in silicon is formed on an object by using a process gas having a phosphorus atom-containing gas added thereto, and a second tungsten silicide layer relatively rich in tungsten is formed on the first tungsten silicide layer, so that a tungsten silicide film is formed. The addition amount of the phosphorus atom-containing gas to the process gas is 0.02 to 0.2% by volume "in terms of a phosphine gas".

    Abstract: PURPOSE: A methode for forming a tungsten silicide film is provided to arrange a decis ion direction of a tungsten silicide by adding a phosphorous atom-containing gas to a process gas. CONSTITUTION: A methode for forming a tungsten silicide film comprises the steps of: forming a first tungsten silicide layer(5) on an object by using a process gas adding a phosphorus atom-containing gas; and forming a second tungsten silicide layer(6) on the first tungsten silicide layer. The first tungsten silicide layer is formed by using the phosphorous atom-containing gas. The second tungsten silicide layer is formed by not using the phosphorous atom-containing gas, or a little amount of phosphorous atom-containing gas.
