Modeling of direct tunneling gate current and gate capacitance in deep submicron MOSFETs with high-K dielectric.

, 2002
Scaling down of MOS device dimensions is accompanied by a decrease in gate-oxide thickness and an increase in substrate doping density. When gate oxide thickness becomes less than 2 nm, a substantial current follows through gate-oxide due to direct ...
