2025-12-25Bow, Warp, and TTV—three critical surface profile parameters of silicon wafers—are indispensable considerations in chip manufacturing. Collectively, these parameters characterize the flatness and thickness uniformity of silicon wafers, exerting a direct impact on numerous key processes in semiconductor fabrication.
