Claim 10:
11. A method of improving the adhesion of a metal-organic interface in an electronic device, comprising:
providing a substrate with a copper interconnect structure;
treating a surface of the copper interconnect structure with a vapor of a chemical composition to form a monolayer coating of the chemical composition on the surface of the copper interconnect structure, wherein the chemical composition includes at least one of
(i.) Phosphoric Acid 2-hydroxyethyl methacrylate ester,
(ii.) Vinyl Phosphonic Acid,
(iii.) N-[3-(Dimethylamino)propyl]methacrylamide,
(iv.) 2-(Diethylamino)ethyl methacrylate,
(v.) 2-(Dimethylamino)ethyl methacrylate,
(vi.) 2-Aminoethyl methacrylate hydrochloride, or
(vii.) 2,3-Epoxypropyl methacrylate; and

after treating the surface of the copper interconnect structure, coating the treated surface with Parylene, wherein the metal-organic interface between the treated surface of the copper interconnect structure and the coated Parylene has improved adhesion.
