Sapphire Wafers & Substrates
Sapphire Wafers & Substrates: Sapphire wafer procurement should identify the required crystal plane, polish side, thickness and edge geometry. Lithography or bonding processes may need tighter bow, warp, TTV and surface criteria. For procurement, describe C/A/R/M orientation, diameter or drawing, thickness, SSP/DSP, optical surface quality, chamfers, coating and inspection method. We discuss product options and inspection requirements case by case, rather than publishing unsupported stock or tolerance guarantees.
