Abstract

A method of forming a ruthenium silicide film on a surface of a substrate includes: forming a ruthenium film to cover a diffusion layer by supplying a gas containing a ruthenium compound to the surface of the substrate where the diffusion layer is exposed; and forming the ruthenium silicide film including RuSiby siliciding the ruthenium film by supplying a gas containing a silicon compound to the substrate while heating the substrate to a temperature within a range of 420 degrees C. or higher and lower than 500 degrees C.
