Semiconductor substrate supports with improved high temperature chucking
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 also include an electrode embedded within the electrostatic chuck body between the heater and the substrate support surface. The substrate support assemblies may be characterized by a leakage current through the electrostatic chuck body of less than or about 4 mA at a temperature of greater than or about 500° C. and a voltage of greater than or about 600 V.
Support Plate for Localized Heating in Thermal Processing Systems
Support plates for localized heating in thermal processing systems to uniformly heat workpieces are provided. In one example implementation, localized heating is achieved by modifying a heat transmittance of a support plate such that one or more portions of the support plate proximate the areas that cause cold spots transmit more heat than the rest of the support plate. For example, the one or more portions (e.g., arears proximate to one or more support pins) of the support plate have a higher heat transmittance (e.g., a higher optical transmission) than the rest of the support plate. In another example implementation, localized heating is achieved by heating a workpiece via a coherent light source through a transmissive support structure (e.g., one or more support pins, or a ring support) in addition to heating the workpiece globally by light from heat sources.
