Claim:
1. A method of processing a substrate disposed atop a substrate support in a physical vapor deposition process chamber, comprising: (a) depositing a dielectric layer to a first thickness atop a first surface of the substrate via a physical vapor deposition process; (b) providing a first plasma forming gas to a processing region of the physical vapor deposition process chamber, wherein the first plasma forming gas comprises hydrogen but not carbon; (c) providing a first amount of bias power to a substrate support to form a first plasma from the first plasma forming gas within the processing region of the physical vapor deposition process chamber; (d) exposing the dielectric layer to the first plasma to adhere monoatomic hydrogen molecules formed in the first plasma to open bonds at a surface of the dielectric layer; and (e) repeating (a)-(d) to deposit the dielectric layer to a final thickness.
