Claim 14:
15. A substrate support for use in a substrate processing chamber, comprising:
a base plate assembly, wherein the base plate assembly includes a central protrusion and a plurality of openings disposed about the central protrusion;
an electrical feedthrough disposed in each of the plurality of openings;
a ceramic puck removably coupled to the base plate assembly via fasteners coupled to a respective floating nut, wherein the ceramic puck has a first side for receiving a substrate and a second side opposite the first side having an interface ring extending from the second side, and wherein, when coupled, the base plate assembly and the ceramic puck contact each other only at an interface between the central protrusion and the interface ring;
an electrode embedded in the ceramic puck and electrically coupled to a first pair of the electrical feedthroughs; and
a first resistive heater embedded in the ceramic puck and electrically coupled to a second pair of the electrical feedthroughs.
