Beschreibung
Zusammenfassung:	A method and apparatus for cleaning a semiconductor wafer processing system comprising a turbomolecular pump. In one embodiment, the invention may be reduced to practice by first supplying a cleaning agent to a chamber; pumping the cleaning agent from the chamber through an the exhaust port; at least partially opening a gate valve; and drawing at least a portion of the cleaning agent through the gate valve and into the turbomolecular pump.
