About the role

onsemi is seeking a self-driven and motivated Senior Failure Analysis Engineer to join our  Product Analysis Lab (PAL). In this hands-on role, you’ll work with a diverse range of onsemi products and collaborate with a team of over 20 passionate engineers and technicians dedicated to delivering “best in class” analytical services and reports. 

This position requires a creative and analytical approach to problem-solving through electrical characterization, fault localization, and the application of advanced analytical tools. We value teamwork, respect, and continuous growth, and we strive for excellence in everything we do.

  • Perform failure analysis on customer returns and internal failures from qualification, design debug, and other evaluations.
  • Isolate failure mechanisms across a broad spectrum of product lines, including complex Image Sensors, ASICs, Analog, Mixed Signal, Digital Logic, SiC, and Smart Discretes.
  • Analyze background data such as ATE logs, X-Ray, and SAT results; characterize failure modes using semiconductor parameter analyzers, oscilloscopes, logic testers, application boards, and other bench equipment.
  • Apply fault localization techniques such as PEM and OBIRCH, integrating CAD layout, schematics, and historical failure mode data.
  • Utilize advanced techniques such as DALS/SDL, LVI/EOFM, LVP/EOP, microprobing, nanoprobing, EBIC, EBAC, scan testing, and ATPG diagnosis to pinpoint failure sites.
  • Oversee material and physical analysis efforts using SEM, FIB, TEM, EDS, FTIR, and other tools to visualize and understand failure mechanisms.
  • Document findings clearly and comprehensively, linking failure mechanisms to failure modes within the 8D problem-solving framework.
  • Develop new processes and techniques to enhance analytical capabilities in a collaborative team environment.
  • Mentor junior engineers in fault localization, electrical testing, and general failure analysis methodologies.
  • Bachelor’s degree or higher in Electrical Engineering or a related field.
  • Minimum of 3 years of experience in a failure analysis or materials analysis lab, or 3 years of experience in a semiconductor or solid-state electronics applications or evaluation engineering role.
  • Must be able to handle very small samples during chemical and other lab operations.
  • Must excel at multi-tasking and working in a team environment.
