The NSX 320 Metrology Series combines macro defect detection with two-dimensional critical dimension metrology and three-dimensional measurement capability.[3]
The NSX 320 Metrology Series handles warped and bonded wafers and supports localized and wafer-level metrology applications.[3]
Metrology and inspection tools in this class are used after deposition, patterning, bonding, or packaging steps to verify geometry, surface condition, and dimensional targets before the next process stage.
The NSX 320 supports advanced packaging applications including copper pillar bumping, TSV, and MEMS.[3]

Such systems can detect a wide range of defects including particles, scratches, voids, residues, pattern distortion, and embedded foreign material. Sensitivity depends on the illumination mode (brightfield, darkfield, or specialized) and the optical resolution of the tool.
Common illumination modes include brightfield, darkfield, and phase contrast. Some systems also offer multiple wavelengths, polarization control, or confocal techniques to enhance detection of specific defect types, such as subsurface defects or pattern edge roughness.
By providing rapid, high-sensitivity defect detection and classification, these tools enable immediate feedback to process engineers. Early identification of excursions or systematic defects allows corrective actions to be taken before many wafers are affected, thereby reducing scrap and improving overall yield.
