Contents on the CD Rom

  • Polycrystalline silicon, also called polysilicon, is a material consisting of small silicon crystals.
  • It differs from single-crystal silicon, used for electronics and solar cells, and from amorphous silicon, used for thin film devices and solar cells.
  • Polycrystalline and paracrystalline phases (see Polycrystal) are composed of a number of smaller crystals or crystallites.
  • Polycrystalline silicon (or semicrystalline silicon, polysilicon, poly-Si, or simply "poly") is a material consisting of multiple small silicon crystals.
  • Polycrystalline cells can be recognized by a visible grain, a “metal flake effect”.
  • Polysilicon is a key component for integrated circuit and central processing unit manufacturers such as AMD and Intel.
  • At the component level, polysilicon has long been used as the conducting gate material in MOSFET and CMOS processing technologies.
  • Polysilicon manufacturing market is in a very fast growth mode.
  • According to Digitimes in July 2011, the total polysilicon production in 2010 was 209,000 tons and first-tier suppliers account for 64% of the market while China-based polysilicon firms have 30% of market share.
  • The total production is likely to increase 37.4% to 281,000 tons by end of 2011.
  • The Hemlock Semiconductor Group, which includes two Dow Corning Corporation joint ventures, Hemlock Semiconductor Group and Hemlock Semiconductor LLC, will invest up to $3.0 billion to expand polycrystalline silicon (polysilicon) production, a key raw material used to manufacture solar cells and semiconductor devices.
  • By 2015, the joint ventures will have increased polysilicon manufacturing capacity by up to 10 times over that 10-year span.
  • In 2009, the global polycrystalline silicon production capacity increased by atleast 65% and China recorded the highest production ramp up of a huge 300% over the previous year.
  • More than 98% of semiconductor-grade polysilicon is produced by the
    trichlorosilane (SiHCl3) distillation and reduction method.
  • For crystal-growth feedstock, the c-Si PV industry has been relying on waste material from the semiconductor Si industry and on secondary polysilicon, the excess or rejected material from electronic-grade polysilicon production.
