  • High thermal stability with a melting point of 2053°C, suitable for rapid thermal cycling.
  • Chemically inert, resistant to most acids and bases except HF and hot H₃PO₄.
  • Superior electrical insulation, maintaining stable dielectric properties at high temperatures.
  • Low defect density, ideal for semiconductor and optoelectronic processing.
  • Available in customizable sizes, orientations, and thicknesses to meet specific requirements.
  • Suitable for diverse applications including semiconductor wafers, optical windows, and protective covers.
FAQ:
  • What is the difference between a raw wafer blank and a finished wafer?
    A raw wafer blank is unpolished with as-cut roughness, while a finished wafer undergoes precision grinding and CMP polishing for a smooth surface.
  • Can the blank be customized?
    Yes, customization options include size, plane orientation, thickness, chamfering, and surface condition to meet specific processing needs.
  • Is sapphire suitable for infrared windows?
    Absolutely, sapphire offers high transmittance from UV to mid-infrared (0.15-5.5 μm), making it ideal for infrared window applications.
