APG-5000 is AKO’s next-generation 300 mm silicon wafer metrology system, built on dual-side synchronous interferometric nanometrology.The system delivers optical resolution far beyond PWG5+ with sub-nanometer precision and seamless upgrade compatibility with PWG2+ and PWG5 platforms. Designed for patterned wafers, APG-5000 accurately measures thickness, flatness, shape, and dual-side nano-scale topography.The system provides advanced monitoring of wafer coating, CMP-induced warp, planar stress, higher-order deformation, and in-plane displacement (IPD), while supporting lithography Overlay error prediction and control. Deployed across R&D and HVM IC fabs, before and after wafer bonding and post-thinning, APG-5000 combines high precision with robust throughput to ensure reliable process control, maintain product quality, and maximize wafer and chip yield
