AB  - In this paper we investigated the feasibility of using a commercial programmable floating-gate MOS transistor (EPAD) as a radiation dosimeter. The results show that EPAD with zero bias have the sensitivity of 9.2 mV/Gy and low fading. EPADs with a higher initial threshold voltage show very good linearity with the radiation dose. After its annealing at 70 °C there is a visible recovery of transfer characteristics due to a parasitic parallel resistive path that occurs during irradiation. Apart from that, the threshold voltage is slightly recovered. The programming time of an EPAD increases with the absorbed dose and depends on gate biasing during irradiation. © 2019 IEEE.

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.

AB  - In this paper it is shown that NBT stress effects in previously irradiated devices are strongly dependent on the total dose received. Namely, in the case of low-dose irradiation the subsequent NBT stress seems to lead to further device degradation. On the other hand, in the case of devices previously irradiated to higher doses, NBT stress seems to have positive role as it practically anneals a part of radiation-induced degradation. The total dose received at which NBT stress almost completely anneals radiation-induced degradation is determined to be around 60 Gy.
