Abstract

In this paper, the single-event effects of Schottky contact super barrier rectifier (SSBR) and conventional super barrier rectifier (SBR) as comparison structure are simulated and discussed. The high-k dielectric has a larger dielectric constant and a larger physical thickness at the same equivalent oxide thickness (EOT). Therefore, it is used to enhance the single-event gate rupture (SEGR) performance of the devices. Simulation results show that the SEGR performance of SSBR and SBR is significantly improved after using high-k dielectric as the gate dielectric. Furthermore, due to the absence of a parasitic bipolar junction transistor (BJT), SSBR has a higher single-event burnout (SEB) performance than conventional SBR. In conclusion, SSBR has a good performance of single-event effect (SEGR and SEB) and is better than that of SBR after using high-k dielectric as the gate dielectric.
