SiON/Ta2O5 stacked gate dielectric exhibits 3-5 orders smaller leakage current than SiO2 at 1.8 nm, while the transistor characteristics such as mobility, Id-Vg, and Id-Vd, are similar to those of SiO2 transistor. N-channel MOSFET with equivalent SiO2 thickness down to 1.8 nm (1.4 nm equivalent due to elimination of poly-Si depletion) is demonstrated. Process effects are also studied for optimum process condition.
