Abstract

A film forming method includes: removing a natural oxide film formed on a front surface of a metal-containing film by supplying a hydrogen fluoride gas to a substrate accommodated in a processing container, the substrate having the metal-containing film formed thereon, and the metal-containing film including no metal oxide film; and forming a silicon film on the metal-containing film by supplying a silicon-containing gas into the processing container, wherein the step of forming the silicon film occurs after the step of removing the natural oxide film.
