Topsil high purity monocrystalline silicon (HPS) is based on float zone growth technology and is primarily used for demanding optoelectronic devices. It is the preferred choice for applications such as infrared detectors, terahertz systems, x-ray mirrors, and silicon lenses, as well as power semiconductors.

Topsil HPS material is characterised by excellent resistivity control and ultra high purity. The products have the following unique material properties: 

  • Highest resistivity range in the market
  • High minority carrier lifetime
  • Low levels of performance degrading impurities

The HPS silicon wafers are available as p- and n-type silicon and in diameters up to 200mm.
