Beschreibung
Zusammenfassung:	Embodiments of substrate supports are provided herein. In some embodiments, a substrate support for use in a chemical vapor deposition (CVD) chamber includes: a pedestal to support a substrate, wherein the pedestal includes a dielectric plate coupled to a pedestal body; an RF rotary joint coupled to the pedestal and having a RF connector; and an RF conduit that extends from the RF connector to the pedestal through a central opening of the pedestal body to provide RF bias to the pedestal; an insulator tube disposed about the RF conduit; and a ground tube disposed about the insulator tube and extending from the RF rotary joint to the pedestal, wherein the insulator tube extends vertically above an upper surface of the ground tube.
