  • 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…  
  • 7. High-Temperature Chemical Vapor Deposition (HTCVD) - The Process  
    The Process A solid component is deposited on the hot surface of a substrate following a chemical reaction from the gas phase. For this to happen, gaseous compounds of the layer components must be…
