Abstract
Exemplary support assemblies may include an electrostatic chuck body defining a substrate support surface. The assemblies may include a support stem coupled with the electrostatic chuck body. The assemblies may include a heater embedded within the electrostatic chuck body. The assemblies may include an electrode embedded within the electrostatic chuck body between the heater and the substrate support surface. The assemblies may include a power transmission rod coupled with the electrode. The power transmission rod may include a material characterized by a coefficient of thermal expansion of less than or about 10×10−6/° C.
