SEMICONDUCTOR SUBSTRATE SUPPORT WITH WAFER BACKSIDE DAMAGE CONTROL

Abstract:

Exemplary support assemblies may include an electrostatic chuck body defining a substrate support surface. The substrate support assemblies may include a support stem coupled with the electrostatic chuck body. The substrate support assemblies may include a heater embedded within the electrostatic chuck body. The substrate support assemblies may include an electrode embedded within the electrostatic chuck body between the heater and the substrate support surface. The substrate support assembly may include a ceramic material characterized by a grain size of less than or about 5 .mu.m.
