HIGH TEMPERATURE MICRO-ZONE ELECTROSTATIC CHUCK

Abstract:

Implementations described herein provide a substrate support assembly. The substrate support assembly has an electrostatic chuck having a workpiece supporting surface and a bottom surface. The substrate support assembly further includes a plurality of layers which has a thermal interface layer. The plurality of layers are disposed below the electrostatic chuck. A cooling base having a top surface, the top surface is disposed below the plurality of layers. A temperature differential across the thermal interface layer is about 150 degrees Celsius when the workpiece supporting surface of the electrostatic chuck is at a temperature of about 300 degrees Celsius.
