COMPOSITION FOR COPPER OXIDE ELECTROLYTIC FORMATION, AND METHOD OF FORMING COPPER OXIDE FILM AND COPPER OXIDE FILM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To form a copper oxide film with uniform film thickness and composition to a complicated deformed shape with a wet process by a method having satisfactory productivity in a composition for copper oxide electrolytic formation and a method of forming a copper oxide film. SOLUTION: The composition for copper oxide electrolytic formation is composed of an aqueous solution at least comprising an organic acid at least having a carboxyl group and a hydroxyl group, and copper ions. Thus, in a region where the production of precipitates such as copper hydroxide is predicted in an aqueous solution comprising no organic acid, a dissolution region where the precipitations are not produced is present, and copper oxide can be formed by a wet process.
