Key Responsibilities Perform Root Cause Analysis (RCA): Lead the systematic investigation of MOSFET failures (e.g., electrical overstress (EOS), electrostatic discharge (ESD), gate oxide integrity, latch-up, thermal runaway, etc.) from both internal qualification tests and customer returns. Utilize Advanced FA Tools: Operate and interpret data from a wide range of failure analysis equipment, including: Electrical characterization (Curve Tracer, Semiconductor Parameter Analyzer) Non-destructive analysis (X-ray, C-SAM, Optical Microscopy) De-processing techniques (Decapsulation, Wet/Delayering, Cross-sectioning) Analytical tools (SEM, EDX, FIB, TEM, OBIRCH, EMMI, TIVA) Document and Report Findings: Prepare detailed FA reports with clear conclusions, supporting data, and actionable recommendations for corrective actions. Collaborate Cross-Functionally: Interface with R&D, product engineering, process integration, and quality team to communicate findings and implement corrective and preventive actions (CAPA). Develop FA Methodologies: Contribute to the development of new FA techniques and best practices tailored to advanced MOSFET technologies (e.g., Trench, SGT, Split Gate, Superjunction). Support Reliability Testing: Assist in the analysis of reliability test failures (HTRB, H3TRB, AC/DC HTOL, etc.) and correlate FA results with reliability models. Continuous Improvement: Proactively identify recurring failure trends and work with engineering teams to improve device robustness, test coverage, and manufacturing processes. Required Qualifications Education: Bachelor’s or Master’s degree in Electrical Engineering, Materials Science, Physics, or a related field. Experience: 5+ years of hands-on failure analysis experience in the semiconductor industry, with a strong focus on power devices, especially MOSFETs. Technical Skills: Strong understanding of MOSFET device physics, structure, and common failure mechanisms. Hands-on experience with semiconductor failure analysis tools (X-ray, C-SAM, Optical Microscopy, decap, cross-section, etc.). Proficiency in electrical characterization and failure isolation techniques. Familiarity with reliability test methods and qualification standards for power devices (AEC-Q101, JEDEC, etc.).
