Abstract

A method for controlling thermal cycling of a faraday shield in a plasma process chamber is provided. The method includes: performing a first plasma processing operation on a first wafer in the plasma process chamber; terminating the first plasma processing operation; performing a first wafer transfer operation to transfer the first wafer out of the chamber; and, during the first wafer transfer operation, applying power to a TCP coil under a plasma limiting condition.
