    摘要: A process is described for depositing a copper film on a substrate surface by chemical vapor deposition of a copper precursor. The process includes treating a diffusion barrier layer surface and/or a deposited film with an adhesion-promoting agent and annealing the copper film to the substrate. Suitable adhesion-promoting agents include, e.g., organic halides, such as methylene chloride, diatomic chlorine, diatomic bromine, diatomic iodine, HCl, HBr and Hl. Processes of the invention provide copper-based films, wherein a texture of the copper-based films is predominantly (111). Such films provide substrates having enhanced adhesion between the diffusion barrier layer underlying the (111) film and the copper overlying the (111) film.
