In this work, we present the comparison of hysteresis behaviors of HfAlON and HfSiON high-k dielectrics at low-temperature and subjected to constant voltage stress (CVS). The VFB instability in the HfAlON and HfSiON gate dielectric were deeply studied. A model is proposed to explain the VFB shift and hysteresis direction in thus two samples. We also treat the CVS voltage and CVS time dependence of...
