Abstract
There is provided a technique that includes: loading a substrate having a metal film composed of a single metal element formed on a surface of the substrate into a process chamber; generating reactive species by plasma-exciting a processing gas containing hydrogen and oxygen; and modifying the metal film by supplying the reactive species to the substrate, wherein in the act of modifying the metal film, the metal film is modified such that a crystal grain size of the metal element constituting the metal film is larger than that before performing the act of modifying the metal film.
