About the role

Key responsibilities & impact

Own and continuously improve the inspection–review–repair (IRP) workflow, ensuring fast, consistent disposition and effective closure of defect signals.
Integrate and analyze diverse defect signals (inspection hits, review outcomes, repair results, holds, rework, OCAP usage, queue time) to identify trends, paretos, and excursion drivers.
Develop and maintain real-time monitoring (RDA) systems and dashboards for defect health, containment status, and flow performance (e.g., holds aging, disposition cycle time, IRP queue health).
Lead root cause analysis and corrective/preventive actions for yield, quality, and flow excursions—spanning tool/process mechanisms, recipe/configuration, handling/contamination, and operational breakdowns.
Partner with inspection, review, and metrology teams to improve signal quality (sensitivity, nuisance reduction, classification accuracy) and to standardize defect taxonomy across tools and workflows.
Support rapid, high-quality dispositions by evaluating impact (printability where applicable), driving clear containment actions, and reducing time-to-decision for holds, rework, and IRP exceptions.
Support qualification and optimization of inspection, review, and repair tools, including recipe governance, matching, and sustaining plans tied to defect and flow performance.
Apply SPC, DOE, and statistical methods to improve both process robustness and workflow robustness (e.g., defect escape reduction, rework reduction, queue-time variation reduction).
Drive OCAP and standard work effectiveness: identify gaps, author or improve response plans, ensure ownership/closure, and verify sustained control through audit-ready evidence.
Own recurring defect/flow review routines (e.g., pareto reviews, aged-hold scrubs) and coordinate cross-functional actions to eliminate chronic constraints in the back end of the photomask manufacturing process.
Collaborate with process, equipment, manufacturing, and operations teams to improve yield, cycle time, and cost through prioritized, closed-loop problem solving.
Document defect mechanisms, control strategies, OCAP/standard work, and lessons learned; maintain clear knowledge bases that accelerate future disposition and root-cause efforts.

Requirements

What you’ll need

5+ years of experience in photomask manufacturing and/or semiconductor manufacturing (yield, process, equipment, or manufacturing engineering).
Hands-on experience in photomask or semiconductor manufacturing environments, including working effectively in/with cleanroom operations.
Working knowledge of photolithography/patterning and how upstream process variation can manifest as downstream inspection, review, repair, or disposition signals.
Ability to transform high-volume, mixed-quality manufacturing data into actionable insights (paretos, excursion detection, defect taxonomy, signal quality metrics) and to communicate results clearly to stakeholders.
Strong fundamentals in structured problem solving and root cause (5-Why, fishbone, fault tree), including containment, corrective action, and verification of effectiveness.
Demonstrated ability to build, improve, and sustain OCAP/standard work (response plans, decision trees, escalation paths) with audit-ready documentation.
Working knowledge of SPC concepts (control charts, capability, common vs. special cause) and experimental methods (DOE), including measurement system considerations.
Proficiency with common analysis and visualization tools (e.g., Excel, Power BI, JMP) and comfort working with manufacturing databases or basic automation/scripting (SQL/Python preferred; equivalent experience acceptable).
Must have a Bachelor's degree in Electrical Engineering, Materials Science, Physics, Chemical Engineering, or related field.
