Abstract
Hot carrier reliability of poly-gated and TiN-gated MOSFETs with HfSiON gate dielectric is studied. For short channel devices, worse degradation of HfSiON occurs at Vg=Vd while oxide devices are degraded more at Vg=Vd/2 similar to oxide control devices. Localized transient charging at the drain comer of the HfSiON layer is proposed to explain the channel length dependence and time dependent relaxation of HC reliability characteristics.
