  • Patent number: 10512954
    Abstract: A method to prevent groundings of polycrystalline silicon rod holders to a reactor plate by the residual polymer in the following manner: first, providing a polycrystalline silicon reactor having a reactor plate with a plurality of silicon rod holders separated from the reactor plate with an insulation; next establishing an electrical circuit from a ground connection on the reactor plate connected to high potential test equipment to a high voltage probe; and finally completing the electrical circuit by contacting the high voltage probe to the holder. By this method any remaining polymer is physically removed as the polymer burns or is ejected by the energetic release caused by mild arcing from the holder to the reactor plate.
    Type: Grant
