Abstract
Various embodiments herein relate to methods, apparatus, and systems for forming an interconnect structure, or a portion thereof, on a substrate. In one example, the method includes receiving the substrate in a processing chamber, the substrate having dielectric material exposed within recessed features formed therein; exposing the substrate to plasma to thereby modify a top surface of the dielectric material; forming a metal oxide barrier layer on the modified top surface of the dielectric material, wherein the metal oxide barrier layer is formed through atomic layer deposition and/or chemical vapor deposition. In certain implementations, one or more additional step may be taken to improve processing results, for example to promote nucleation and/or adhesion of relevant layers.
