英文摘要The total ionizing dose (TID) effect is one of the main causes of the performance degradation/failure of semiconductor devices under high-energy gamma-ray irradiation. In special, the concentration of doubly-hydrogenated oxygen vacancy (a case study of Vo gamma H2) in the oxide layer seriously exacerbates the TID effect. Therefore, we developed a dynamic model of mobile particles and fixed defects by solving the rate equations and Poisson's equation simultaneously, to reveal the contribution and influence mechanisms of Vo gamma H2 on the TID effect of MOS devices. We found that Vo gamma H2 can directly and indirectly promote the formation of V-o gamma(+) and Vo gamma H+ , respectively, which can increase the electric field near the Si/SiO2 interface and reduce the threshold voltage of silicon MOS devices accordingly. Controlling Vo gamma H2 with a concentration below 10(14) cm(-3) can suppress the adverse TID effects. The results are much helpful for analyzing the microscopic mechanisms of the TID effect and designing new MOS devices with high radiation-hardening.
