ABSTRACT:
A film is applied to a substrate in accordance with a predetermined pattern by applying a solution of a copolymer of fluoropolymers dissolved in a solvent onto the surface of the substrate; curing and annealing the solution to boil off the solvent and form a copolymer film on the substrate; depositing a thin metal film on the copolymer film; patterning the thin metal film by a photoresist etching process to expose the underlying copolymer film in accordance with the predetermined pattern; removing the exposed copolymer film so that the underlying substrate is exposed in accordance with the predetermined pattern; removing any remaining thin metal film; depositing the film to the remaining copolymer film and exposed substrate; then removing the remaining copolymer film and any film applied thereon by ultrasonic cleaning.
