    Abstract: Exemplary semiconductor processing systems may include a chamber body comprising sidewalls and a base. The systems may include a substrate support extending through the base of the chamber body. The substrate support may include a support plate defining a plurality of channels through an interior of the support plate. Each channel of the plurality of channels may include a radial portion extending outward from a central channel through the support plate. Each channel may also include a vertical portion formed at an exterior region of the support plate fluidly coupling the radial portion with a support surface of the support plate. The substrate support may include a shaft coupled with the support plate. The central channel may extend through the shaft. The systems may include a fluid source coupled with the central channel of the substrate support.
