    • A method for processing polycrystalline silicon workpieces to form size distributions of polycrystalline silicon pieces suitable for use in a Czochralski-type process includes: (1) preparing a polycrystalline silicon workpiece by a chemical vapor deposition process; (2) fracturing the polycrystalline silicon workpiece into a mixture of polycrystalline silicon pieces, where the polycrystalline silicon pieces have varying sizes; and (3) sorting the mixture of polycrystalline silicon pieces into at least two size distributions. Step (2) may be carried out by a thermal shock process. Step (3) may be carried out using a rotary indent classifier. A rotary indent classifier for performing the method includes: (i) a rotating cylinder having a circumferential edge with indents arrayed in increasing size from a first end of the cylinder to a second end of the cylinder, and (ii) a conveyor running longitudinally adjacent the cylinder, for conveying silicon pieces from the first end of the cylinder to the second end of the cylinder.

    • A process for the deposition of pure semiconductor silicon by reductive chemical vapor decomposition of a precursor silane, the process comprising:

      (1) forming and depositing semiconductor silicon on a heated substrate;
      (2) separating a mixture enriched in lower-boiling silanes from the effluent gases from the decomposition/ deposition reactor;
      (3) combining the mixture enriched in lower-boiling silanes with additional tetrachlorosilane, so that there is present in the combination less than about 1.0 mole hydrogen bonded to silicon per mole of total silicon;
      (4) passing the combination through a bed of a solid disproportionation catalyst to facilitate disproportionation of hydrogen-containing silanes and chlorine-containing silanes to produce a stream that is reduced in content of silane, chlorosilane and dichlorosilane and increased in content of trichlorosilane; and
      (5) isolating and separating the trichlorosilane.
    • 一种用于通过前体硅烷的还原化学气相分解沉积纯半导体硅的方法,该方法包括:(1)在加热的衬底上形成和沉积半导体硅; (2)从分解/沉积反应器的流出气体中分离富含低沸点硅烷的混合物; (3)将富含低沸点硅烷的混合物与另外的四氯硅烷组合,使得组合中存在小于约1.0摩尔与每摩尔总硅结合的氢的氢键; (4)使组合物通过固体歧化催化剂床,以促进含氢硅烷和含氯硅烷的歧化,以产生降低硅烷,氯硅烷和二氯硅烷含量并增加三氯硅烷含量的物流; 和(5)分离和分离三氯硅烷。 [R
