Responsibilities

Maintain, calibrate, and optimize automated defect inspection and metrology tools to ensure robust performance in a high‑volume MEMS manufacturing environment.
Monitor tool health, detection sensitivity, measurement accuracy, and false‑call rates; drive corrective actions when deviations occur.
Analyze defect trends, measurement stability, and metrology outputs to identify yield‑impacting issues.
Perform defect labeling, categorization, and annotation to enable development and refinement of deep learning–based defect detection models.
Prepare and curate representative datasets, ensuring quality, consistency, and traceability for model training and validation.
Partner with data science and automation teams to evaluate model performance and implement improved algorithms in production.
Work closely with upstream and downstream modules—including lithography, planarization, etch, and plating—to troubleshoot issues and identify defect sources.
Participate in cross‑module process improvement projects to reduce defectivity and improve overall process robustness.
Provide metrology expertise during new process introductions, tool qualifications, and engineering evaluations.
Create, maintain, and update work instructions (WIs), standard operating procedures (SOPs), and process documentation related to metrology and inspection operations.
Train operations personnel on metrology tool usage, inspection criteria, and process requirements.
Support daily production activities, including responding to tool alarms, providing rapid defect analysis, and ensuring continuity of manufacturing flow.
