Silicon & Polysilicon

Production of high-purity silicon and polysilicon used in the fabrication of semiconductors has been evolving to meet the increasing quality needs of device manufacturers. Purity of the silicon wafer substrate has an impact on the ability of integrated device manufacturers to maintain and/or increase yields. With geometries getting smaller, contamination in the silicon wafer are getting stricter. Metals (including boron), silica, TOC and particles are the most common contaminants that need to be reduced.
