    Abstract: A substrate support assembly to support a semiconductor substrate in a processing chamber includes a baseplate arranged in the processing chamber, a dielectric layer arranged on the baseplate to support the semiconductor substrate, an electrode disposed in the dielectric layer along a horizontal plane, and a plurality of channels to carry a fluid. The plurality of channels are disposed in the dielectric layer along the horizontal plane on a side of the electrode facing away from the baseplate.

    Abstract: A system for estimating stress on a component of a processing chamber during a process includes a plurality of sensors configured to sense temperatures at a plurality of locations of the component during the process and a controller a controller configured to interpolate the temperatures to estimate a temperature distribution across the component and to estimate the stress on the component during the process. A method of estimating stress on a component of a processing chamber during a process includes sensing temperatures at a plurality of locations of the component during the process, interpolating the temperatures to estimate a temperature distribution across the component, and estimating the stress on the component during the process.

    Abstract: A baseplate of a substrate support assembly includes a cavity between an upper region, a lower region, and sidewalls of the baseplate, a plurality of pillars arranged in the cavity between the upper and lower regions, an inlet to supply a liquid to the cavity, and an outlet to vent vapor of the liquid. In another implementation, a baseplate of a substrate support assembly includes a first channel arranged in the baseplate, a second channel arranged above the first channel, a plurality of vertical channels connecting the first channel to the second channel, an inlet to supply a liquid to the first channel, and an outlet to vent vapor of the liquid from the second channel.
