Abstract

We propose a new double-box model of the oxide conduction band of MOS devices, aiming to quantitatively predict the gate current across ultra-thin oxides. Simulations nicely fit the experimental quantum oscillations of the gate current in the Fowler-Nordheim tunnelling regime. The oscillation period of the gate current has been empirically correlated with the oxide thickness. The low-field Stress Induced Leakage Current can be fitted by our model as well, by inserting oxide traps mediating an inelastic trap-assisted tunnelling.
