Senior Electron Microscopy Engineer

The successful candidate will be a subject-matter expert in FIB, SEM, EDX/EDS, TEM/STEM, HRTEM, and electron diffraction, with strong expertise in advanced FIB sample preparation and semiconductor defect analysis. A key expectation of this position is the ability to identify structural defects, understand their formation mechanisms, and connect microscopy observations to semiconductor materials, fabrication processes, device performance, and reliability.

What You Will Do

Perform advanced electron microscopy analysis using FIB, SEM, EDX/EDS, TEM/STEM, HRTEM, and electron diffraction to identify defects, interfaces, compositional abnormalities, and failure mechanisms. Develop advanced FIB sample-preparation methods, including site-specific cross-sectional TEM lamella preparation, plan-view TEM preparation, low-damage thinning, and preparation of challenging semiconductor device structures.

Why It Might Be a Fit

The successful candidate will have strong knowledge of crystallography, semiconductor defects, and defect-formation mechanisms, with demonstrated ability to identify defects and determine their likely materials or process origins. Experience with InP, InGaAs, InGaAsP, DFB lasers, EMLs, quantum-well structures, buried heterostructures, and semiconductor laser failure analysis is highly desirable.

Requirements

• Ph.D. in Materials Science, Physics, Electrical Engineering, or a related field with 5+ years of relevant industrial experience, or equivalent industrial experience demonstrating comparable technical expertise.
• Recognized expertise in advanced electron microscopy, including FIB, SEM, EDX/EDS, TEM/STEM, HRTEM, and electron diffraction, with deep hands-on experience in advanced FIB sample preparation such as plan-view TEM specimens and site-specific cross-sectional lamellae.
• Strong knowledge of crystallography, semiconductor defects, and defect-formation mechanisms, with demonstrated ability to identify defects and determine their likely materials or process origins.
• Strong knowledge of semiconductor devices and manufacturing processes, preferably compound semiconductor lasers, including epitaxy, e-beam lithography, photolithography, wet and dry etching, PVD, CVD, metallization, and epitaxial regrowth.
