Abstract:
1. A method of forming an oxide film on a surface of a base material constituted from an inorganic material, the oxide film being constituted from a material containing an oxide of the inorganic material as a major component thereof, the method comprising: preparing the base material; subjecting the surface of the base material to surface treatment, wherein the subjecting the surface of the base material to surface treatment includes applying moisture onto the surface of the base material and bringing the surface at the base material into contact with plasma; supplying a process liquid containing alcohol onto the surface of the base material to form a liquid film of the process liquid thereon after the surface treatment has been carried out; producing an oxide of the inorganic material through a reaction of the inorganic material with the alcohol in the liquid film; and eliminating the process liquid remaining in the liquid film to form the oxide film on the surface of the base material.
