Integrated production from CZ crystal growth to wafering process

 


Our Wafers

The silicon wafers provided by SUMCO are made from high-purity monocrystalline silicon ingots, manufactured by the CZ (Czochralski) crystal growth process.

  • Ingots up to 200mm in diameter are manufactured for our wafering process under the highest level of quality control
  • A monocrystalline ingot is sliced to thicknesses of around 1mm and the surfaces are polished to a mirror finish. As a result, the wafers are exceptionally flat and clean

Wafer Specification
