Yield Defect Metrology Technician

About This Role

• Position Overview As the Yield Defect Metrology Technician, you will be instrumental in supporting defect review activities, including defect classification, validation, and hold lot disposition.
• You will help maintain quality excellence standards while contributing to the delivery of standardized, high-quality execution.
• Your primary focus will be the accurate classification of defects captured by multiple inspection systems.
• Through precise defect classification and systematic analysis, you will play a vital role in minimizing defect noise that can obscure true yield-limiting issues, drive data-driven systematic defect reduction initiatives, and maintaining the optimal balance between rigorous quality control standards and manufacturing efficiency requirements.
• Your work will directly contribute to yield improvement efforts, cost reduction initiatives, and overall manufacturing excellence.
• Key Responsibilities 1.
• Defect Classification and Analysis Review and Analyze defect images captured by diverse metrology tools.
• Accurately classify defects based on documented defect specification.
• Distinguish between true defects requiring disposition action and false positives or nuisance defects.
• Maintain proficiency across multiple inspection platforms and adapt classification criteria to different tool capabilities and imaging conditions 2.
• Defect Validation Verify defect classifications against established criteria and specifications Partner with Layer Owner to ensure consistent defect categorization approaches Prevent over-rejection scenarios by accurately identifying non-critical defects and cosmetic variations that do not impact product performance.
• Avoid under-rejection situations by ensuring killed defects are properly identified and flagged for disposition.
• Feed manually classified data to improve Automatic Defect Classification (ADC) accuracy. 3.
• Hold Lot Disposition Ensure strict compliance in review and disposition of hold lots based on documented Out-of-Control Action Plans (OCAP) Ensure proper documentation and traceability of all disposition decisions.
• Collaborate with Layer Owner to update and refine OCAP procedures based on emerging defect patterns 4.
• First Level Defect Analysis Perform comprehensive first level defect analysis as the initial point of technical review for all flagged defects.
• Document initial findings and recommendations to support Layer Owner analysis and decision-making processes.
