Summary: | Embodiments of substrates supports for use in process chambers are provided herein. In some embodiments, a substrate support includes: a dielectric plate having a first side configured to support a substrate having a given diameter and including an annular groove disposed in the first side, wherein the annular groove has an inner diameter that is less than the given diameter and an outer diameter that is greater than the given diameter, wherein the dielectric plate includes a chucking electrode; an insert ring disposed in the annular groove of the dielectric plate; and an edge ring disposed on the dielectric plate, wherein the edge ring has an inner diameter that is greater than the given diameter and less than the outer diameter of the annular groove such that the edge ring is disposed over a portion of the insert ring. |
