Responsibilities

Operate and support metrology and inspection equipment in full compliance with EHS standards, cleanroom protocols, and equipment safety requirements; proactively identify and mitigate safety and equipment-related risks.
Lead installation, qualification, recipe development, and production release of automated optical inspection tools; ensure stable performance, image fidelity, and correlation to failure mechanisms.
Own fab microscopy platforms (optical and related techniques), enabling rapid defect review, root cause analysis, and engineering decision-making for development and high-volume production.
Support and optimize flying probe test equipment and methodologies; ensure data accuracy, correlation to downstream inspection, and effective feedback to process engineering.
Own profilometry systems and measurement techniques to characterize film thickness, topography, and critical surface features; ensure measurement repeatability and relevance to process control.
Own tool set and process used to form and measure mems probe tips.
Analyze inspection and metrology data to identify yield limiters, defect trends, and process excursions; lead technical investigations using structured problem-solving methods and partner with module owners on corrective actions.
Develop and maintain SPC strategies for metrology and inspection steps.
Generate and maintain work instructions, qualification reports, control plans, and best practices for metrology and inspection systems.
