摘要:
A structure of a copper conductor is obtained by oxidizing copper film formed on the surface of a substrate, and by heat treating the same in a reducing atmosphere, whereby only the surface layer portion of the oxidized copper film is reduced to become copper. The copper film of a conductor is formed on the surface of the substrate with the oxidized copper film interposed therebetween. As a result, an adhesion of the copper film to the surface of the substrate is enhanced.
