Research on temperature sensitivity of Single-event Transient pulse width in 28-nm bulk technology

Abstract

Abstract The influence of temperature on single-event transient (SET) pulse width has always been a hot issue in the field of anti-irradiation. Based on 3D-TCAD simulation, the temperature sensitivity of the SET pulse width of 28-nm bulk devices has been studied. The simulation results show that the electrical characteristics of the device shows an anti-temperature effect, but the worst case of SET pulse width still occurs at high temperature rather than low temperature. The influence of the triple-well structure on the temperature sensitivity of the SET pulse width has also been studied. The N+ deep well can significantly increase the SET pulse width when hitting NMOS device and enhance the temperature sensitivity of the SET pulse width. The research content of this article will provide reference for the design of radiation resistant chip.
