Abstract
Systems and methods are provided for determining a clean endpoint time for a current run of a chamber. The clean endpoint time for the current run may be determined by determining that a chamber parameter, such as a chamber pressure, has stabilized. Historical clean endpoint time data is updated by adding the clean endpoint time for the current run of the chamber. A recommended clean endpoint time is then determined for the chamber based on the updated historical clean endpoint time data.
