Problem
In advanced semiconductor manufacturing, precise 3D metrology is critical for process control, but traditional methods often lack the resolution and throughput required for in-line monitoring of increasingly complex nano-scale devices. Existing techniques may also be destructive, preventing their use for on-device measurement and real-time process optimization.
Solution
Nearfield Instruments provides high-throughput atomic force microscopy (AFM) systems that enable non-destructive, 3D metrology at the atomic scale, directly within semiconductor fabrication lines. Their QUADRA system, enhanced with Lightning Mode, delivers rapid, high-resolution imaging and data analysis, facilitating real-time process control and yield optimization. By providing accurate, non-destructive measurements on actual devices, Nearfield Instruments allows manufacturers to correlate metrology data with device performance, accelerating time-to-yield and improving high-volume manufacturing (HVM) for advanced memory and logic devices. The system addresses the challenges posed by shrinking geometries, complex 3D structures, and advanced packaging techniques like High Bandwidth Memory (HBM).
