发明名称 Selective ruthenium deposition on copper materials
摘要 Embodiments of the invention provide processes for selectively forming a ruthenium-containing film on a copper surface over exposed dielectric surfaces. Thereafter, a copper bulk layer may be deposited on the ruthenium-containing film. In one embodiment, a method for forming layers on a substrate is provided which includes positioning a substrate within a processing chamber, wherein the substrate contains a copper-containing surface and a dielectric surface, exposing the substrate to a ruthenium precursor to selectively form a ruthenium-containing film over the copper-containing surface while leaving exposed the dielectric surface, and depositing a copper bulk layer over the ruthenium-containing film.
