Thin copper film directly bonded polyimide film and method of manufacturing the same

Abstract

Provided is a thin copper film directly bonded polyimide film in which a thin copper film is directly and strongly connected to a polyimide film. This thin copper film directly bonded polyimide film includes a polyimide film modified by bonding an organic silane compound having a cyano group represented by formula —Si(R—CN)n (wherein R represents alkyl group having 1 to 6 carbon atoms and n represents a positive number from 1 to 3) to a carbon atom on the surface of the polyimide film, and a thin copper film directly bonded to the modified surface of the polyimide film.

Dependencies are inferred from the claim text.
