PECVD SiNx passivation with more than 8 MV/cm breakdown strength for GaN-on-Si wafer stress management
In this work, multi-layer PECVD SiNx/SiNx and SiNx/SiOy passivations are developed featuring very high soft breakdown strength and tunable stress properties, which would allow for stress engineering and wafer bow minimization. AlGaN/GaN-on-Si wafers (150 mm) with very low initial bow (<5 μm) are...
