Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device, with which current leakage via residual metal generated on the sidewall by the silicidation of a polysilicon conductive member is prevented. SOLUTION: A sidewall, composed of a nitride film, is formed on a conductive member which is composed of a polysilicon layer formed on a semiconductor wafer (step 1). Then, an oxide film is formed on the surface of the sidewall (step 2). Next, a metal film for silicidation is deposited on the main surface of the wafer including the conductive member by a sputtering method (step 3). Then, the metal film is silicidized by heat treating the wafer (step 4), thereby a silicide layer is formed, at least on the upper part of the conductive member of the polysilicon. Next, the wafer is immersed in diluted HF (diluted hydrofluoric acid) solution, to remove unreacted metal film (step 5). The silicide layer is stabilized by a re-annealing process (step 6).
