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.

在热载子效应后，接著进行正偏压温度不稳定的量测方法，从随时间变动的临界电压以及次临界摆幅，发现临界电压的变动趋势与临界摆幅变动趋势不符合，表示二氧化铪的原生缺陷补捉是造成临界电压变动的主因，而临界摆幅的变动也可得知有氟，氮处理元件具有比较好的介面可靠度。
