Mask inspection equipment examines reticle patterns for defects, pattern fidelity, and other deviations that can affect downstream lithography.
A reticle or mask inspection system typically uses optical metrology and image comparison methods to evaluate mask features against expected geometry.
Reticle mask inspection sits in the lithography supply chain before the mask is used on the wafer line.
Reticle mask inspection supports process control by screening the patterning source before exposure and by helping reduce defect transfer into printed wafer features.
Reticle mask inspection is used in photomask quality control for semiconductor manufacturing.
Reticle mask inspection is used to support defect detection, pattern verification, and mask release decisions.
