  • Publication number: 20080261405
    Abstract: An oxygen-free hydrogen plasma ashing process particularly useful for low-k dielectric materials based on hydrogenated silicon oxycarbide materials. The main ashing step includes exposing a previously etched dielectric layer to a plasma of hydrogen and optional nitrogen, a larger amount of water vapor, and a yet larger amount of argon or helium. Especially for porous low-k dielectrics, the main ashing plasma additionally contains a hydrocarbon gas such as methane. The main ashing may be preceded by a short surface treatment by a plasma of a hydrogen-containing reducing gas such as hydrogen and optional nitrogen.
