• 4. Physical Vapor Transport (PVT) - The Process  
  The Process In the PVT process polycrystalline Silicon Carbide (SiC) undergoes sublimation at the source at a high temperature (1,800–2,600 °C) and low pressure. In a carrier gas (e.g. Argon),…  
• 5. Float Zone (FZ) - The Process  
  The Process In a chamber with a controlled atmosphere, a clean polycrystalline Silicon rod (source rod) is positioned above a high-frequency induction coil. When the high-frequency current is…  
• 6. Czochralski Process (Cz) - The Process  
  The Process To begin with, high-purity polycrystalline silicon is placed in the Silica crucible of a single crystal pulling system and then melted in a controlled atmosphere (Argon) using a…

• 10. Overview  
  To obtain pure silicon, the oxygen contained in the silica sand (SiO2) has to be extracted with the help of carbon. Since silicon and oxygen are atomically very closely related, carbon and oxygen in…
