    摘要: Embodiments of the invention provide processes to selectively form a cobalt layer on a copper surface over exposed dielectric surfaces. In one embodiment, a method for capping a copper surface on a substrate is provided which includes positioning a substrate within a processing chamber, wherein the substrate contains a contaminated copper surface and a dielectric surface, exposing the contaminated copper surface to a reducing agent while forming a copper surface during a pre-treatment process, exposing the substrate to a cobalt precursor gas to selectively form a cobalt capping layer over the copper surface while leaving exposed the dielectric surface during a vapor deposition process, and depositing a dielectric barrier layer over the cobalt capping layer and the dielectric surface. In another embodiment, a deposition-treatment cycle includes performing the vapor deposition process and subsequently a post-treatment process, which deposition-treatment cycle may be repeated to form multiple cobalt capping layers.

    摘要: Embodiments of the invention described herein generally provide methods for forming cobalt silicide layers and metallic cobalt layers by using various deposition processes and annealing processes. In one embodiment, a method for forming a metallic silicide containing material on a substrate is provided which includes forming a metallic silicide material over a silicon-containing surface during a vapor deposition process by sequentially depositing a plurality of metallic silicide layers and silyl layers on the substrate, depositing a metallic capping layer over the metallic silicide material, heating the substrate during an annealing process, and depositing a metallic contact material over the barrier material. In one example, the metallic silicide layers and the metallic capping layer both contain cobalt. The cobalt silicide material may contain a silicon/cobalt atomic ratio of about 1.9 or greater, such as greater than about 2.0, or about 2.2 or greater.
