Job Description
We are seeking a highly motivated Wafer Optical Metrology Engineer to support advanced thinfilm magnetic read/write head manufacturing and process control initiatives. The engineer will be responsible for developing, optimizing, and sustaining optical metrology methodologies used in lithography and pattern alignment processes for wafer manufacturing. This role focuses on improving measurement robustness, accuracy, throughput, tool performance, process capability, and yield through data-driven analysis and collaboration with process integration, lithography, and manufacturing teams.
ESSENTIAL DUTIES AND RESPONSIBILITIES
- Develop, qualify, and maintain optical metrology recipes and measurement strategies for semiconductor wafer manufacturing processes.
- Analyze parametric data trends, identify process excursions, and implement corrective actions in collaboration with process, integration, and yield engineering teams.
- Perform statistical analysis and process capability studies (SPC, Cp/Cpk, regression analysis, DOE).
- Drive continuous improvement initiatives for precision, throughput, and automation.
- Develop scripts and data analysis tools using Python, JMP, or similar platforms.
- Generate technical reports, presentations, and documentation for engineering reviews.
- Support technology transfers and new process development for advanced products.
- Crosstrain within Metrology Engineering to build broad technical competence and provide support coverage across teams.
