After hot carrier stress, devices were evaluated by using positive bias temperature instability test. With different trends in the time evolution of threshold voltage shift and sub-threshold swing degradation, it is found that electron trapping in the HfO2 is the major reason for the threshold voltage variation. Compared to control devices, devices with fluorine and nitrogen exhibit good passivation at the interface. Devices were measured at an elevated temperature.
