Core Responsibilities

Primary Functions

  • Conduct comprehensive, hands-on failure analysis on complex electronic components, modules, and systems to precisely identify the root cause of failures originating from customer returns, manufacturing yield loss, and reliability testing.
  • Expertly operate and interpret data from a wide range of advanced analytical laboratory equipment, including Scanning Electron Microscopy (SEM), Focused Ion Beam (FIB), Energy Dispersive X-ray Spectroscopy (EDX), and X-ray imaging systems.
  • Perform detailed electrical fault isolation using techniques such as Optical Beam Induced Resistance Change (OBIRCH), Thermal and Laser Voltage Probing (TIVA/LVP), and emission microscopy (EMMI) to pinpoint failure locations on integrated circuits.
  • Execute meticulous physical analysis, including mechanical de-capsulation, chemical de-processing, cross-sectioning, polishing, and metallographic examination to expose and characterize failure mechanisms at the die and package level.
  • Author clear, concise, and highly detailed technical reports documenting the complete failure analysis investigation, including background, analytical procedures, findings, and definitive root cause determination.
  • Present and effectively communicate complex failure analysis findings, conclusions, and actionable recommendations to diverse, cross-functional teams including Design, Product, Reliability, and Manufacturing engineering.
  • Collaborate directly with design and process engineering teams to drive corrective and preventive actions (CAPA), providing critical feedback to improve product robustness and prevent future occurrences of identified failure modes.
  • Develop, validate, and document innovative failure analysis techniques and methodologies to enhance the lab's capabilities for characterizing new technologies and challenging failure mechanisms.
  • Manage the failure analysis workflow, prioritizing incoming requests based on business impact and ensuring timely closure of all investigation cases.
  • Provide technical mentorship and guidance to junior engineers and technicians within the failure analysis lab, fostering a culture of continuous learning and technical excellence.
  • Interface with customers and suppliers on technically challenging issues, providing clear status updates and presenting final analysis results in a professional and compelling manner.
  • Analyze electrical characterization data from bench-top setups and automated test equipment (ATE) to correlate electrical signatures with physical failure modes.
  • Maintain and troubleshoot failure analysis laboratory equipment, coordinating with vendors for service, calibration, and upgrades to ensure maximum uptime and capability.
  • Drive the 8D problem-solving process by providing the critical "D4: Determine Root Cause" component, ensuring a data-driven approach to problem resolution.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis to identify subtle failure trends and statistical process control (SPC) excursions.
  • Contribute to the organization's data strategy by ensuring failure analysis data is captured, structured, and accessible for broader reliability and quality analysis.
  • Collaborate with business units to translate future product and technology needs into requirements for new analytical tools and laboratory capabilities.
  • Participate in sprint planning and agile ceremonies within the broader Quality and Engineering teams to ensure alignment on priorities and deliverables.
  • Support New Product Introduction (NPI) activities by performing early life failure analysis and providing design-for-reliability (DfR) feedback.
  • Conduct competitor product teardowns and construction analysis to benchmark technology and identify potential design or manufacturing weaknesses.
  • Stay current with industry standards (e.g., JEDEC, AEC-Q100) and emerging failure mechanisms and analytical techniques through continuous learning and participation in industry forums.
