By annealing (heat treatment) this in a nitrogen-containing atmosphere, a substance which makes an alloy with copper is diffused on the surfaces (upper surface and side surfaces) of the copper alloy film to couple with nitrogen in the atmosphere. By this reaction, the copper gradually becomes a purer and at the same time, a nitride 16 is formed on the surface of the film 14. This silicide film acts as a barrier against the oxidation of a copper wiring 18. Moreover, as the copper alloy film is provided on the diffused barrier metallic film, Cu can be prevented from diffusing in an insulating film 10 and an Si substrate.
