发明名称 CMP PAD THICKNESS AND PROFILE MONITORING SYSTEM
摘要 In one embodiment a method is provided for maintaining a substrate processing surface. The method generally includes performing a set of measurements on the substrate processing surface, wherein the set of measurements are taken using a displacement sensor coupled to a processing surface conditioning arm, determining a processing surface profile based on the set of measurements, comparing the processing surface profile to a minimum profile threshold, and communicating a result of the profile comparison.
