  • Publication number: 20110274836
    Abstract: Embodiments of the present invention relate to apparatus and methods of preventing build-up of explosive material in vacuum forelines of deposition systems. A cleaning gas such as nitrogen trifluoride (NF3) may be introduced into a particulate collection device including a catchpot having a configuration comprising a sloped interior surface area that maximizes the amount of reactive silicon-containing particles that are exposed to and react with the cleaning gas stream to form silicon tetrafluoride (SiF4) and other non-reactive by-products. The degree of slope of the interior surface area may be based upon the angle of repose of the silicon-containing particles. The gaseous silicon tetrafluoride (SiF4) and other non-reactive by-products can flow out of the catchpot and into the exhaust stream towards a vacuum pump. The apparatus and method may also avoid accumulation of highly reactive and highly explosive particulates in catchpots.
