Modern sapphire wafer manufacturing requires crystal growth, orientation, coring, slicing, grinding, polishing, cleaning, and inspection. Each stage influences flatness, subsurface damage, crystal defects, and suitability for epitaxy, optics, sensors, or technical components.
Fused silica wafers begin with high-purity silicon dioxide and are produced through controlled melting or synthetic deposition. The route affects hydroxyl content, metallic impurities, ultraviolet transmission, homogeneity, and thermal behavior, so every fused silica wafer material is not identical.
Glass wafers are precision substrates used where electrical insulation, optical transmission, chemical resistance, or controlled thermal expansion matters more than conductivity. The correct glass wafer substrate material depends on process temperature, wavelength, bonding method, thickness tolerance, and surface finish.
