  • Integration scheme for advanced BEOL metallization including low-k cap layer and method thereof
    Publication number: 20030134495
    Abstract: An advanced back-end-of-line (BEOL) metallization structure is disclosed. The structure includes a diffusion barrier or cap layer having a low dielectric constant (low-k). The cap layer is formed of amorphous nitrogenated hydrogenated silicon cabride, and has a dielectric constant (k) of less than about 5. A method for forming the BEOL metallization structure is also disclosed, where the cap layer is deposited using a plasma-enhanced chemical vapor deposition (PE CVD) process. The invention is particularly useful in interconnect structure comprising low-k dielectric material for the inter-layer dielectric (ILD) and copper for the conductors.
