KLA - Model Surfscan SP7 XP -Unpatterned Wafer Defect Inspection System

The Surfscan SP7XP unpatterned wafer inspection system identifies defects and surface quality issues that affect the performance and reliability of leading-edge logic and memory devices. It supports IC, OEM, materials and substrate manufacturing by qualifying and monitoring tools, processes and materials, including those used for EUV lithography. Using a DUV laser and optimized inspection modes, the Surfscan SP7XP delivers ultimate sensitivity for advanced node R&D and the throughput to support high volume manufacturing. Complementary detection modes, including the phase contrast channel (PCC) and normal illumination (NI), detect unique defect types for bare wafers, smooth and rough films, and fragile resists and litho stacks. Image based defect classification (IBC) using revolutionary machine learning algorithms support faster time to root cause, while the Z7™ classification engine supports unique 3D NAND and thick film applications.
