Abstract:
In one implementation, a showerhead assembly is provided. The showerhead assembly comprises a first electrode having a plurality of openings therethrough and a gas distribution faceplate attached to a first lower major surface of the electrode. The gas distribution plate includes a plurality of through-holes for delivering process gases to a processing chamber. The gas distribution plate is divided into a plurality of temperature-control regions. The showerhead assembly further comprises a chill plate positioned above the electrode for providing temperature control and a plurality of heat control devices to manage heat transfer within the showerhead assembly. The heat control device comprises a thermoelectric module and a heat pipe assembly coupled with the thermoelectric module. Each of the plurality of heat control devices is associated with a temperature control region and provides independent temperature control to its associated temperature control region.

Claim (Index 9):
