Method and system for controlling bake plate temperature in a semiconductor processing chamber

摘要

A method of operating a bake plate disposed in a semiconductor processing chamber having a face plate opposing the bake plate includes providing a temperature control signal to the bake plate and measuring a face plate temperature associated with the face plate. The method also includes determining a difference between the face plate temperature and a predetermined temperature and modifying the temperature control signal provided to the bake plate in response to the determined difference.
