HIGH THERMAL CONDUCTIVITY WAFER SUPPORT PEDESTAL DEVICE

摘要

A support pedestal device for an electrostatic chuck includes a base housing defining an internal cavity, and a base insert disposed proximate the internal cavity of the base housing. A fluid pathway is formed in the internal cavity and includes a plurality of linear-parallel cooling channels separated by corresponding plurality of linear-parallel cooling fins, a fluid supply channel, and a fluid return channel. A cooling fluid flows through the fluid supply channel, through the plurality of linear- parallel cooling channels, and back through the fluid return channel to cool the support pedestal device.
