Abstract
The invention provides a vacuum processing system comprising a vacuum processing chamber and a turbo-molecular pump having a rotor and/or stator comprised of metal matrix composites. Another aspect of the invention provides a turbo-molecular pump having a rotor and/or a stator comprised of metal matrix composites. Because metal matrix composites are able to withstand higher operating temperatures than the aluminum alloys currently used in rotors and stators, the rotor vanes and the stator vanes that are made of metal matrix composites can provide a higher exhaust capacity with faster rotor rotations.
