Abstract:
A plasma processing system useful for processing semiconductor substrates comprising:a plasma processing chamber having an interior space bounded by a chamber sidewall;a substrate support on which a substrate is processed within the interior space, the chamber sidewall being spaced outwardly of a periphery of the substrate support;a gas supply through which process gas can be supplied to the interior space during processing of the substrate;an energy source which can energize the process gas in the interior space into a plasma state during processing of the substrate;a ceramic liner supported between the chamber sidewall and the periphery of the substrate support; anda heater which heats the liner by radiant heating, wherein the heater is located in a gap between the ceramic liner and the chamber sidewall and wherein the heater is separated from an outer periphery of the liner by an open space.
