Abstract
A film structure includes low-k dielectric films and N—H base source films such as barrier layer films, etch-stop films and hardmask films. Interposed between the low-k dielectric film and adjacent N—H base film is a TEOS oxide film which suppresses the diffusion of amines or other N—H bases from the N—H base source film to the low-k dielectric film. The film structure may be patterned using DUV lithography and a chemically amplified photoresist since there are no base groups present in the low-k dielectric films to neutralize the acid catalysts in the chemically amplified photoresist.
