Abstract: A substrate processing system includes a hinge assembly configured to allow a substrate support and an RF bias assembly to slide, from a docked position to an undocked position, relative to other components of a processing chamber. A make-break connector is configured to supply fluid to at least one of the substrate support and the RF bias assembly. The make-break connector includes a first portion including a first fluid passage connected to a first conduit. A second portion includes a second fluid passage connected to a second conduit. The first fluid passage in the first portion fluidly communicates with the second fluid passage in the second portion. The first portion is configured to slide with the substrate support and the RF bias assembly relative to the second portion and the other portions of the processing chamber. The first portion is located inwardly relative to the second portion.

Abstract: An apparatus is provided. The apparatus comprises a processing chamber. A substrate support is within the processing chamber, wherein the substrate support is in thermal contact with a substrate. A cooling system cools the substrate support. The cooling system comprises a first refrigeration system. The first refrigeration system comprises a first refrigerant inlet for receiving the first refrigerant from a first refrigerant source outside of the refrigeration system, wherein the first refrigerant is at a first pressure, a first throttle, wherein the first throttle allows a controlled expansion of the first refrigerant, wherein the expansion of the first refrigerant cools the first refrigerant, a first heat transfer system, for absorbing heat and transferring heat to the cooled first refrigerant, and a first refrigerant return for directing the first refrigerant from the first refrigeration system at a second pressure away from the first refrigeration system.

Abstract: A system for controlling temperature of a substrate, which is arranged on a substrate support assembly, includes first and second sources to respectively supply a fluid at first and second temperatures at a fixed flow rate. First and second three-way proportional valves receive the fluid from the first and second sources, mix first portions of the received fluid to supply the fluid having a predetermined temperature to the substrate support assembly at a predetermined flow rate, and return second portions of the received fluid to the first and second sources. A third three-way proportional valve receives the fluid from the substrate support assembly and returns the received fluid to the first and second sources. A controller controls the first and second valves to supply the fluid to the substrate support assembly and controls the third valve to divide the fluid between the first and second sources.
