Claim:
1. A substrate support of a plasma processing chamber, comprising: a first layer of a non-metal material, the first layer having upper and lower surfaces, the upper surface configured to support a substrate thereon during processing of a substrate in the plasma processing chamber; a second layer of an electrically conductive material bonded to the lower surface of the first layer; a void space extending through the entire first and second layers; a tubular sleeve fitted in the void space in the second layer such that the second layer is not exposed in the void space; wherein one end of the tubular sleeve is coplanar with facing surfaces of the first layer and the second layer and the other end of the tubular sleeve is coplanar with a lower surface of the second layer and the tubular sleeve has an exposed inner surface with an inner diameter equal to the inner diameter of the void space in the first layer; wherein at least one ESC electrode is embedded in the first layer; wherein the second layer has a thickness from 0.5 to 5 mm and at least one film heater attached to the lower surface of the second layer; and a base plate attached to the lower surface of the second layer wherein the base plate includes embedded fluid channels and is configured to be supplied with RF power during processing of a substrate when the substrate support is installed in the plasma processing chamber.
