  • Publication number: 20080135742
    Abstract: Method and system for pumping a hyperthermal neutral beam source is described. The pumping system enables use of the hyperthermal neutral beam source for semiconductor processing applications, such as etching processes. An embodiment is described having a neutral beam source coupled to a processing chamber through a neutralizing grid. Control is provided by separately pumping the neutral beam source and the processing chamber.
