A method of processing a substrate is provided. The substrate includes an etching target region and a patterned region. The patterned region is provided on the etching target region. In the method, an organic film is formed on a surface of the substrate. Subsequently, the etching target region is etched by plasma generated from a processing gas. The organic film is formed in a state that the substrate is placed in a processing space within a chamber. When the organic film is formed, a first gas containing a first organic compound is supplied toward the substrate, and then, a second gas containing a second organic compound is supplied toward the substrate. An organic compound constituting the organic film is generated by polymerization of the first organic compound and the second organic compound.
