Claim 15:
16. A support pedestal comprising:
a support member including a resistive layer having a plurality of zones, a routing layer, a main substrate having opposing surfaces, and a plurality of conductive vias, wherein:
the plurality of zones are defined by a plurality of independently controllable resistive heating elements,
the resistive layer and the routing layer being disposed on the opposing surfaces of the main substrate,
the resistive layer and the routing layer are connected by the plurality of conductive vias, and
the plurality of conductive vias extend through the main substrate; and
a plurality pairs of electric terminals, each pair of electric terminals connected to a corresponding one of the plurality of independently controllable resistive heating elements via the routing layer and a corresponding pair of the plurality of conductive vias.
