Metrology Process Engineer

Primary Duties & Responsibilities


* Own and sustain metrology processes that support both production and new product development.


* Operate and maintain key metrology systems including ellipsometry, spectroscopic reflectometry, CD-SEM, AFM, Nanospec, particle inspection, and four-point probe.


* Monitor tool health and measurement stability through regular SPC and MSA reviews.


* Perform GR&R and correlation studies to ensure data accuracy and repeatability across tools and operators.


* Partner with process module owners (photo, etch, metallization, etc.) to define measurement plans and provide data-driven feedback for process optimization.


* Support daily production by reviewing metrology data, identifying trends, and troubleshooting excursions or out-of-control conditions.


* Develop and maintain calibration routines, control limits, and standard work procedures.


* Participate in cross-functional problem-solving efforts using structured methods such as DOE, FMEA, and 8D.


* Help define metrology requirements and control plans for new processes and technologies.


* Train technicians and junior engineers on tool operation, data interpretation, and measurement best practices.

Education & Experience


* Bachelor's or Master's degree in Materials Science, Electrical Engineering, Physics, or a related field.


* Minimum 5 years of experience in a semiconductor fab, ideally working with GaAs, InP, or other compound semiconductor technologies.


* Experience linking metrology data to electrical or optical test performance.


* Participation in yield improvement, DOE, or continuous improvement programs.


* Experience evaluating and qualifying new metrology tools or software platforms.
