| 内容記述 | In order to develop highly radiation-tolerant SiC MOSFETs, we investigated the dependence of the gamma-ray radiation response on the gate oxide thickness and nitridation processes, used for oxide growth and p-well implantation. SiC MOSFETs with a thick gate oxide (60 nm) showed a rapid decrease in the threshold voltage shift ⊿Vth of more than 400 kGy, and transitioned to the normally-on state at lower doses than those with a thin gate oxide (35 nm). The MOSFETs with gate oxides treated with lower concentrations of N2O (10%) demonstrated a higher radiation tolerance (⊿Vth, channel mobility, and subthreshold swing) than with a 100% N2O treatment. The MOSFETs with more p-well implantation steps (three steps) showed a smaller negative shift of the threshold voltage relative to those implanted with two steps. | |||||
