Patent ID: 7993460

Claim:
A substrate support useful in a reaction chamber of a plasma processing apparatus, the substrate support comprising: a ceramic member; a metallic heat transfer member overlying the ceramic member, the heat transfer member having a maximum thickness of about ¼ inch, the heat transfer member including at least one flow passage through which a liquid can be circulated to heat and cool the heat transfer member; an electrostatic chuck overlying the heat transfer member, the electrostatic chuck having a support surface for supporting a substrate in a reaction chamber of a plasma processing apparatus; a source of temperature controlled liquid in flow communication with the at least one flow passage; and a controller operable to control the volumetric flow rate and/or the temperature of the liquid circulated through the at least one flow passage, so as to control heating and cooling of the heat transfer member at a rate of from about 0.25-2° C./sec, wherein heating is performed solely by the heat transfer member.
