On the Trap Assisted Stress Induced Safe Operating Area Limits of AlGaN/GaN HEMTs
This experimental study reports a systematic investigation of Safe Operating Area limits in AlGaN/GaN HEMT using sub-mu s pulse characterization with on the fly Raman and CV characterization to probe defect and stress evolution across the device. Influence of a recess depth on SOA boundary is analyzed. Post failure analysis corroborates well with the failure physics unveiled in this work
