Claim 14:
15. A method of processing a substrate, comprising:
clamping a substrate to a substrate support surface of a chuck body using a chucking force, wherein:
the substrate support surface defines a plurality of protrusions that extend upward from the substrate support surface;
the substrate support surface defines a first region and a second region that are depressed relative to a primary region of the substrate support surface; and
the first region and the second region are spaced apart from one another about the substrate support surface;
a subset of the plurality of protrusions are disposed within each of the first region and the second region;

flowing a precursor into a processing chamber;
generating a plasma of the precursor within a processing region of the processing chamber; and
depositing a material on the substrate.
