摘要： Methods for depositing a contact metal layer in contact structures of a semiconductor device are provided. In one embodiment, a method for depositing a contact metal layer for forming a contact structure in a semiconductor device is provided. The method comprises performing a cyclic metal deposition process to deposit a contact metal layer on a substrate and annealing the contact metal layer disposed on the substrate. The cyclic metal deposition process comprises exposing the substrate to a deposition precursor gas mixture to deposit a portion of the contact metal layer on the substrate, exposing the portion of the contact metal layer to a plasma treatment process, and repeating the exposing the substrate to a deposition precursor gas mixture and exposing the portion of the contact metal layer to a plasma treatment process until a predetermined thickness of the contact metal layer is achieved.

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.
