Beschreibung
Zusammenfassung:	A substrate support in a substrate processing system includes a baseplate, a ceramic layer, and a bond layer. The ceramic layer is arranged on the baseplate to support a substrate. The bond layer is arranged between the ceramic layer and the baseplate. A seal is arranged between the ceramic layer and the baseplate around an outer perimeter of the bond layer. The seal includes an inner layer formed adjacent to the bond layer and an outer layer formed adjacent to the inner layer such that the inner layer is between the outer layer and the bond layer. The inner layer comprises a first material and the outer layer comprises a second material.
