Reducing wafer processing defects requires control from raw-material selection through cutting, grinding, polishing, cleaning, inspection, and packaging. Defects rarely come from one isolated operation. Scratches, pits, particles, chips, thickness variation, bow, and subsurface cracks often develop through several connected process conditions.
Suitable wafer size depends on processing equipment, device dimensions, material availability, production volume, and the cost of maintaining acceptable yield. Larger wafers can hold more devices, but they are not automatically the most economical option.
Wafer pricing is determined by the interaction of material type, diameter, thickness, orientation, surface finish, geometric tolerances, processing complexity, inspection level, and order quantity. Two wafers with the same diameter may have very different costs when one requires standard polishing and the other requires tight TTV, ultra-low roughness, custom shaping, and detailed inspection.
