Senior Semiconductor Metrology Engineer

Responsibilities

• Be a key member of the semiconductor metrology lab, supporting R&D and production manufacturing.
• Develop, qualify, and maintain measurement recipes for inline and offline metrology tools (e.g., thickness, roughness, composition, stress, defect quantification, etc.).
• Support metrology process control for materials moving through the production line, ensuring measurement accuracy, repeatability, and throughput.
• Analyze large and complex datasets to identify trends, process excursions, and root causes; communicate findings clearly to process engineering and operations teams.
• Define, track, and report key performance indicators (KPIs) related to metrology capabilities, tool utilization, cycle time, and measurement uncertainty.
• Collaborate closely with process engineering, manufacturing, quality, and equipment teams to support process development and yield improvement.
• Support tool qualifications, gauge R&R studies, and continuous improvement initiatives for measurement methodologies.
• Establish best practices for data integrity, documentation, and statistical analysis.
• Support technology transfers from development to high-volume manufacturing.
• Interface with equipment vendors to maintain and service all instruments.
• Mentor junior engineers and technicians; provide technical leadership within the metrology function.

Technical Skills

• Strong background in semiconductor metrology techniques such as optical, X-ray, electron-beam, and bulk/surface analysis methods (e.g., XRD, SEM, AFM, wafer level defect mapping and classification).
• Experience setting up, optimizing, and maintaining measurement recipes on commercial metrology platforms.
• Advanced data analysis skills, including statistical process control (SPC), design of experiments (DOE), and uncertainty analysis.
• Proficiency with data analysis tools and programming environments (e.g., Python, MATLAB, JMP).
• Understanding of semiconductor manufacturing flows and inline metrology integration.
• Familiarity with yield analysis, process control methodologies, and manufacturing metrics.
• Ability to translate complex measurement data into actionable insights for cross-functional stakeholders.
• Strong documentation, presentation, and technical communication skills.

Education

• Typically requires a minimum of 7 years of related experience with a Bachelor’s degree; or 5 years and a Master’s.degree or a Ph.D.w 3 years exp in Materials Science, Physics, Electrical Engineering, Chemical Engineering, or a closely related field.
