Abstract: A system and method for cleaning a preclean process chamber in between wafer processing. The internal pressure of the preclean process chamber is reduced to a first pressure and a first gas that consists of oxygen and an inert or noble gas, is introduced into the chamber.

Internal pressure is then reduced to a second pressure, less than the first, and the first gas is continued into the chamber. Plasma is then generated using the first gas at the second pressure. Thereafter, a second gas, consisting of an oxygen-free inert or noble gas, is introduced into the chamber at the second pressure, following which plasma is generated within the chamber using only the second gas.
