摘要: Methods and apparatus for controlling a processing system are provided herein. In some embodiments, a method of controlling a processing system may include operating a vacuum pump coupled to a process chamber at a first baseline pump idle speed selected to maintain the process chamber at a pressure equal to a first baseline pump idle pressure; monitoring the pressure in the process chamber while operating the vacuum pump at the first baseline pump idle speed; and determining whether the first baseline pump idle pressure can be maintained in the process chamber when the vacuum pump is operating at the first baseline pump idle speed.
