Abstract(in English) | Recent advances of GaN/SiC power devices, RF/MMIC (monolithic microwave integrated circuit) devices, and also Image Sensors have been increasing the importance of SiO2 and SiN-based THICK dielectric films (> ~20 nm). Because of their thicknesses and relatively low integrities, carrier charging under electrical stress prevents us from appropriately understanding their TDDB characteristics. This paper demonstrates the charging-induced dynamic stress relaxation (CiDSR) effect causes the misunderstanding of TDDB statistics in thick SiO2 and of the TDDB model of SiN films. Then, the constant-delta E model is proposed as an appropriate model for SiN film by suppressing the CiDSR effect. Furthermore, the anomalous thickness dependence of the Weibull slope is reported in both SiO2 and SiN films and the Generalized model is proposed to explain it by combining the conventional percolation model and the constant-delta E model. |
