What it is
How it works
General reference — not yet source-verifiedInspection may be performed in transmission mode, where light passes through the reticle, or in reflection mode, depending on the layer and defect type. The system uses advanced algorithms to classify detected defects by size, type, and location, enabling engineers to assess their impact on wafer yield.
Where it fits in the process flow
General reference — not yet source-verifiedReticle inspection systems are used after the photomask is fabricated and before it is released for production use in a wafer fab. The inspected reticle is then loaded into a stepper or scanner for wafer exposure. Periodic reinspection of reticles during their lifetime is also performed to catch any contamination or degradation that may occur from repeated handling and cleaning.
The inspection step sits between reticle manufacturing and wafer lithography, serving as a gate to ensure only defect-free masks are used. Downstream processes rely on the inspection results to decide whether a reticle can be repaired or must be scrapped.
