TEMPERATURE-TUNED SUBSTRATE SUPPORT FOR SUBSTRATE PROCESSING SYSTEMS

A system for controlling a temperature of a substrate during treatment in a substrate processing system comprises a substrate support including first and second components, first and second heaters, and first and second heat sinks. The first component includes an upper surface at least partially defining a center zone. The second component is arranged radially outside of and below the first component. The second component includes an upper surface at least partially defining a radially-outer zone. The first and second components are spaced apart and define a gap between them. The first and second heaters are configured to heat the first and second components, respectively. The first heat sink has one end in thermal communication with the first component. The second heat sink has one end in thermal communication with the second component.
