Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
General reference — not yet source-verifiedMacro inspection tools are used for full-wafer surface inspection to detect large-area defects without high magnification, typically as part of in-line process monitoring.
How it works
General reference — not yet source-verifiedMacro inspection systems employ bright-field or dark-field illumination coupled with a camera system to capture whole-wafer images.
The captured images are compared against a reference—such as a design database or an adjacent die—using pattern-recognition algorithms to flag anomalies.
Where it fits in the process flow
General reference — not yet source-verifiedMacro inspection is performed after photoresist develop, after chemical-mechanical planarization, after etch, or after deposition to catch gross defects before the next processing step.
The tool sits in the metrology and inspection workflow, upstream of review scanning electron microscopy or final yield analysis, and downstream of the unit process being monitored.
Applications
General reference — not yet source-verifiedApplications include defect monitoring of photoresist uniformity, edge beads, scratches, particles, stains, and pattern integrity on patterned wafers.
The tool is used in logic, memory, and advanced packaging fabs for high-throughput macro defect detection.
