    摘要: A substrate support pedestal comprises an electrostatic chuck, a cooling base, a gas flow passage, a porous plug, and a sealing member. The electrostatic chuck comprises body having a cavity. The cooling base is coupled to the electrostatic chuck via a bond layer. The gas flow passage is formed between a top surface of the electrostatic chuck and a bottom surface of the cooling base. The gas flow passage further comprises the cavity. The porous plug is positioned within the cavity to control the flow of gas through the gas flow passage. The sealing member is positioned in a groove formed in the cooling base and configured to form a seal between the cooling base and one or both of the porous plug and the body of the electrostatic chuck.

    摘要: 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.

    摘要: Embodiments described herein relate to a substrate support assembly. The substrate support assembly includes an ESC base assembly having a base channel disposed therein, a facility plate, the facility plate coupled to the ESC base assembly with a vacuum region therebetween, and a seal assembly. The seal assembly includes an upper flange coupled to the base channel of the ESC base assembly, the upper flange disposed in the facility plate, a lower flange coupled to the upper flange, the lower flange disposed in the facility plate, a gasket disposed between the upper flange and the lower flange, and an insulator tube coupled to the lower flange. A passage is connected to the base channel, the passage is defined by connected openings of the upper flange, the gasket, the lower flange, the insulator tube, and the base assembly.

    摘要: 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 refrigerant channel disposed therein, and a facility plate having a coolant channel disposed therein. The facility plate includes a plate portion and a flange portion. The plate portion is coupled to the ESC base assembly and the flange 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 flange portion of the facility plate, and the seal assembly.
