20130112134 | Method and Systems for Characterization and Production of High Quality Silicon - Computer controlled quality control methods for manufacturing high purity polycrystalline granules are introduced. Polycrystalline silicon granules are sampled and converted into single crystal specimen in computer controlled system, eliminating the need of human operator in controlling the processing parameters. Single crystal silicon test samples, then characterized by FTIR and other standard analysis, are therefore more representative of the starting granular silicon. | 05-09-2013 |
