Beschreibung
Zusammenfassung:	Exemplary substrate support assemblies may include a chuck body defining a substrate support surface. The substrate support surface may define a plurality of protrusions that extend upward from the substrate support surface. The substrate support surface may define an annular groove and/or ridge. A subset of the plurality of protrusions may be disposed within the annular groove and/or ridge. The substrate support assemblies may include a support stem coupled with the chuck body.
