Abstract :
We have systematically investigated the VFB shift in the case of the stacked bi-layer high-k dielectrics with paying attention to the high-k/IL-SiO2 interface. We demonstrate for the first time that VFB shifts are determined predominantly by the high-k/IL-SiO2 interface, while the gate/high-k interface plays little role.
