Characterization and Reliability Engineer

About this role

Responsibilities

• Own and develop the electrical characterization methodology for CNF-MIM capacitors including:
• C–V, I–V, breakdown, and leakage measurements
• Frequency-dependent characterization and loss measurements
• Temperature-dependent characterization
• Drive compact modeling and circuit-level evaluation of CNF-MIM capacitors:
• Development or calibration of simplified/compact capacitor models based on measured electrical behavior
• Use of SPICE or equivalent circuit simulation tools to predict and model the behavior of CNF-MIM capacitors
• Correlation of simulation results with measured data to refine models and support device and stack optimization
• Design and execute reliability test plans for CNF-MIM capacitors and dielectric stacks, including:
• Time-dependent dielectric breakdown (TDDB)
• Endurance and cycling tests and retention measurements
• High-temperature storage / HTOL-like tests and thermal cycling
• Evaluation of stability vs. bias, temperature, and environment
• Analyze measurement and reliability data using appropriate statistical tools:
• Weibull analysis, confidence intervals, and lifetime extrapolation
• Correlation of reliability metrics with process and structural param
