Beschreibung
Zusammenfassung:	The present disclosure generally provides for a system and method for measuring one or more characteristics of one or more substrates in a multi-station processing system using one or more metrology modules at a plurality of metrology stations. In one embodiment, a system controller is configured to cause the multi-station processing system to perform a method that includes processing a plurality of substrates at a plurality of processing stations, advancing one or more of the plurality of substrates to a respective metrology station, measuring one or more characteristics of the plurality of substrates at the respective metrology station, determining a processing performance metric based on the one or more characteristics, comparing the processing performance metric to a tolerance limit to determine if an out of tolerance condition has occurred, and adjusting one or more processing parameters when it is determined that an out of tolerance condition has occurred.
