Simplified quantitative stress-induced leakage current (SILC) model for MOS devices
چکیده انگلیسی

A simplified quantitative model for the steady-state component of stress-induced leakage current (SILC) in MOS capacitors with ultrathin oxide layers has been developed by assuming a two-step inelastic trap-assisted tunneling (ITAT) process as the conduction mechanism. By using our model, we reduced the time of numerical calculations of SILC to 17% of the standard method while maintaining a high accuracy of the results. We also confirmed that the SILC component must not be neglected when calculating the gate current in modern devices, especially at low fields. Our simplified model helped us to investigate the dependence of SILC on the oxide field and the oxide thickness. We also shed some light on the reasons that cause the peak in the SILC–oxide thickness relation.
