A-LFNA Success Story: Enabling Reliability Physics Insight via 1/f Noise
Case Studies
The Keysight E4727B Advanced Low-Frequency Noise Analyzer (A-LFNA) enables non-destructive reliability characterization by leveraging 1/f noise measurements to reveal underlying device degradation mechanisms. This case study highlights research conducted at Imec on IGZO thin-film transistors and advanced Gate-All-Around nanosheet devices. By combining low-frequency noise analysis with DC characterization, researchers identified band tail state broadening as the primary cause of degradation in IGZO TFTs and demonstrated wafer-level benchmarking of gate-stack quality in nanosheet technologies. A-LFNA provides a direct link between electrical behavior and reliability physics, helping users extract effective trap density, distinguish channel and dielectric effects, accelerate root-cause analysis, support predictive reliability assessment, and optimize semiconductor processes for next-generation device development.
