AB  - n this paper, the e®ects of successively applied static/pulsed negative bias temperature (NBT)stress and irradiation on commercial p-channel power vertical double-di®used metal-oxidesemiconductor (VDMOS) transistors are investigated. To further illustrate the impacts of thesestresses on the power devices, the relative contributions of gate oxide charge (Not) and interfacetraps (Nit) to threshold voltage shifts are shown and studied. It was shown that when irradi-ation without gate voltage is used, the duration of the pre-irradiation static NBT stress has aslightly larger e®ect on the radiation response of power VDMOS transistors. Regarding the factthat the investigated components are more likely to function in the dynamic mode than thestatic mode in practice, additional analysis was focused on the results obtained during thepulsed NBT stress after irradiation. For the components subjected to the pulsed NBT stressafter the irradiation, the e®ects ofNotneutralization andNitpassivation (usually related toannealing) are more enhanced than the components subjected to the static NBT stress, becauseonly a high temperature is applied during the pulse-o® state. It was observed that in devicespreviously irradiated with gate voltage applied, the decrease of threshold voltage shift is sig-ni ̄cantly greater during the pulsed NBT stress than during the static NBT stress

AB  - The effects of bias temperature stress and irradiation in commercial p-channel power VDMOS transistors were investigated. In order to additionally elucidate the effects that take place in these power devices during the irradiation after the NBT stress, the relative contributions of gate oxide charge (ΔVot/ΔVTH) and interface traps (ΔVit/ΔVTH) to the threshold voltage shifts are presented and analyzed. It was found that in the case of irradiation without gate voltage the duration of the preirradiation NBT stress had a more pronounced impact on the radiation response of power VDMOS transistors, and that the contribution of the oxide trapped charge plays a more pronounced role in components previously NBT stressed for 1 hour than in those stressed for 1 week.

AB  - In this paper we provide an overview of instabilities observed in commercial power VDMOSFETs subjected to irradiation, NBT stress, and to consecutive exposure to them. The results have indicated that irradiation of previously NBT stressed devices leads to additional threshold voltage shift, while NBT stress effects in previously irradiated devices depend on the gate bias applied during irradiation and on the total dose received. This points to the importance of the order of applied stresses, indicating that for proper insight into the prediction of device behaviour not only harsh conditions, but also the order of exposure have to be considered. It has also been shown that changes in the densities of oxide trapped charge and interface traps during spontaneous recovery after each of applied stresses can be significant, thus leading to additional instability, even though the threshold voltage seems to remain stable, pointing to the need for clarifying the responsible mechanisms.
