This role is for a Senior Semiconductor Metrology Engineer to be a key member of the semiconductor metrology lab, supporting R&D and high-volume manufacturing. The engineer will develop, qualify, and maintain measurement recipes for inline and offline metrology tools, support metrology process control, analyze large datasets, define and track KPIs, and collaborate with various teams. The position also involves supporting technology transfers, interfacing with vendors, and mentoring junior staff.

Requirements

• 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.

Responsibilities

• Be a key member of the semiconductor metrology lab, supporting R&D and high-volume 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 phase to full production.
• Interface with equipment vendors to maintain and service all instruments.
• Mentor junior engineers and technicians; provide technical leadership within the metrology function.
