  • Publication number: 20100180426
    Abstract: Methods and apparatus for reducing particles in a gas delivery system are provided herein. In some embodiments, a method of fabricating a gas distribution apparatus, such as a gas distribution plate or nozzle, for a semiconductor process chamber includes providing a gas distribution apparatus having one or more apertures adapted to flow a gas therethrough. A slurry is flowed through the one or more apertures to remove a damaged surface from sidewalls of the plurality of apertures. In some embodiments, the gas distribution apparatus may be oxidized before or after flowing the slurry through the one or more apertures. In some embodiments, the gas distribution apparatus may be conditioned by providing RF power to the gas distribution plate for a desired period of time.
