Abstract
A method and apparatus is disclosed for automatically adjusting a recovery time for a processing system to recover from an idle mode to a normal operation mode in order to improve the efficiency of resource utilization, such as energy consumption. The processing system can be one that is used in semiconductor manufacturing, and include a process tool supported by an auxiliary device, such as a vacuum pump or abatement device. A number of parameters can be controlled to adjust the recovery time of the auxiliary device. One or more of those parameters can be increased or decreased based on comparison between a measured, actual recovery time and a predetermined, target recovery time, at the end of each recovery cycle. As such, the actual, measured recovery time can gradually converge with the predetermined, target recovery time, thereby optimizing the resource utilization of the processing system.
