What it is

The Onto Innovation NSX 320 is a metrology and inspection system for semiconductor manufacturing.[1][3]

The NSX 320 is part of a metrology series that combines macro inspection with three-dimensional metrology for advanced packaging applications.[3]

How it works

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]

Where it fits in the process flow

General reference — not yet source-verified

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.

Applications

The NSX 320 supports advanced packaging applications including copper pillar bumping, TSV, and MEMS.[3]

Frequently asked questions

What types of defects can an optical inspection system like the NSX 320 detect?General reference — not yet source-verified

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.

What illumination modes are commonly available on such optical inspection tools?General reference — not yet source-verified

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.

How does an optical inspection system contribute to yield management?General reference — not yet source-verified

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.
