/Multi-zone Heater With Minimum Rf Loss
Abstract

Exemplary substrate support assemblies may include an electrostatic chuck body defining a substrate support surface that defines a substrate seat. The substrate support assemblies may include a support stem coupled with the electrostatic chuck body. The substrate support assemblies may include an upper heater embedded within the electrostatic chuck body. The upper heater may include a center heater zone and one or more annular heater zones that are concentric with the center heating zone. The substrate support assemblies may include a lower heater embedded within the electrostatic chuck body at a position below the upper heater. The lower heater may include a plurality of arcuate heater zones.
