The support assembly includes a non-metallic body having a support surface for supporting the substrate and an integral peripheral outer portion extending outwardly from and substantially surrounding the support surface of the substrate. The support assembly also includes at least one electrode carried by the non-metallic body for electrostatically coupling a substrate to the support surface of the non-metallic body and a base coupled to the underside of the non-metallic body for the transfer of heat between the non-metallic body and the base.
