FAQ:
  • How is a sapphire wafer blank different from an unpolished wafer?
    A sapphire wafer blank is the raw slice cut to wafer size without lapping or grinding, while an unpolished wafer has been lapped flat but not polished.
  • Why do manufacturers buy sapphire wafer blanks instead of finished wafers?
    Wafer blanks are more economical and allow full control over the finishing process, ensuring the final wafer meets internal standards.
  • Can sapphire wafer blanks be customized?
    Yes, custom diameters, thicknesses, and crystal orientations are available, with optional edge preparation.
  • Can they be used directly for LED or optical applications?
    No, they must be lapped and polished before serving as LED substrates or optical-grade materials.
