Method and apparatus for improving silicon processing efficiency

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