Surfscan® SP7 XP Unpatterned Wafer Defect Inspection System The Surfscan® SP7 XP unpatterned wafer inspection system facilitates qualification and monitoring of processes and tools for IC, wafer, equipment and materials manufacturers for ≤5nm logic and advanced memory design nodes. With industry-best 12.5nm sensitivity and high throughput, the Surfscan SP7 XP provides a single tool solution for both R&D pathfinding applications and process monitoring during high volume manufacturing. Built on the industry-standard Surfscan® platform, the Surfscan SP7 XP delivers ultimate sensitivity to critical defects and enhanced defect classification for bare wafers, smooth and rough films, and fragile resists and litho stacks, including those used for EUV lithography. By discovering and identifying critical defects and surface quality issues, the Surfscan SP7 XP enables faster identification of process and tool issues, driving faster ramp, higher yield and improved fab profitability. As an extension of the Surfscan SP7, the Surfscan SP7 XP incorporates new hardware technologies and innovative algorithms that enable enhanced capability, including: Ultimate sensitivity for advanced design node R&D pathfinding by IC fabs, wafer houses and equipment manufacturers High throughput for cost-effective monitoring during high volume manufacturing of advanced design node devices Capture of unique defects types using new inspection modes for support of a broad range of process monitoring applications Image based defect classification using revolutionary machine learning algorithms for faster time to
