Abstract
Embodiments of the present disclosure are related to improved methods for forming an interconnect structure in a substrate. In one implementation, the method includes providing a substrate comprising a metal region and a dielectric region surrounding the metal region, selectively forming a cobalt-containing alloy cap layer on the metal region by exposing the substrate to a first precursor and a second precursor, the first precursor and the second precursor are selected from a group consisting of an aluminum-containing precursor, a cobalt-containing precursor, a ruthenium-containing precursor, a manganese-containing precursor, and a tungsten-containing precursor, wherein the first precursor is different from the second precursor.
