Wafer inspection systems are metrology and inspection tools used to examine wafer surfaces and patterned structures for defects, contamination, damage, and process variation. Wafer inspection tools commonly support process monitoring, engineering analysis, and quality control across multiple manufacturing stages.

Wafer inspection systems generally use controlled illumination, imaging optics, and camera capture to observe surface condition and pattern features on a wafer. Wafer inspection systems commonly present images and measurement views through operator software, and upgraded hardware or software can extend control, image handling, or analysis functions.

Wafer inspection tools sit alongside fabrication and development steps that need verification of wafer condition before or after patterning, deposition, etch, cleaning, or planarization. Wafer inspection tools are used between process modules to detect excursions early and to confirm that wafers remain suitable for subsequent manufacturing steps.

Wafer inspection systems are applied to defect review, surface quality checks, and process troubleshooting on semiconductor wafers and related substrate work. Wafer inspection systems also support engineering evaluation of process-induced changes, visual confirmation of wafer features, and general inspection tasks in device manufacturing and research environments.
