Own and optimize the inspection–review–repair (IRP) workflow for photomask manufacturing.
Analyze inspection data to identify defect trends, paretos, and excursion drivers.
Develop and maintain real-time defect monitoring (RDA) systems and dashboards.
Drive root cause analysis and corrective actions for yield and defect excursions.
Partner with inspection and metrology teams to improve defect detection sensitivity and classification accuracy.
Evaluate defect printability and impact to support disposition decisions (repair vs accept vs scrap).
Support qualification and optimization of inspection, review, and repair tools.
Apply SPC, DOE, and statistical analysis to improve process robustness.
Collaborate with process, equipment, and manufacturing teams to improve yield, cycle time, and cost.
Document defect mechanisms, control strategies, and process improvements.
