Coherent • Sherman, TX

1d

About The Position

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.
