SUBSTRATE PROCESSING WITH RAPID TEMPERATURE GRADIENT CONTROL
摘要:
A substrate processing chamber comprises an electrostatic chuck comprising a ceramic puck having a substrate receiving surface and an opposing backside surface. In one version, the ceramic puck comprises a thickness of less than 7 mm. An electrode is embedded in the ceramic puck to generate an electrostatic force to hold a substrate, and heater coils in the ceramic puck allow independent control of temperatures at different heating zones of the puck. A chiller provides coolant to coolant channels in a base below the ceramic puck. A controller comprises temperature control instruction sets which set the coolant temperature in the chiller in relation prior to ramping up or down of the power levels applied to the heater.
