CRYOGENIC ELECTROSTATIC CHUCK

Embodiments described herein relate to a substrate support assembly which enables a cryogenic temperature operation of an electrostatic chuck (ESC) so that a substrate disposed thereon is maintained at a cryogenic processing temperature suitable for processing while other surfaces of a processing chamber are maintained at a different temperature. The substrate support assembly includes an electrostatic chuck (ESC), an ESC base assembly coupled to the ESC having a base channel disposed therein, and a facility plate having a facility channel disposed therein. The facility plate includes a plate portion and a wall portion. The plate portion is coupled to the ESC base assembly and the wall portion coupled to the ESC with a seal assembly. A vacuum region is defined by the ESC, the ESC base assembly, the plate portion of the facility plate, the wall portion of the facility plate, and the seal assembly. 本文所述实施例涉及一种基板支撑组件，所述基板支撑组件实现静电吸盘(ESC)的低温操作，使得设置在静电吸盘(ESC)上的基板被维持在适用于处理的低温处理温度，同时将处理腔室的其他表面维持在不同的温度。基板支撑组件包含：静电吸盘(E
