摘要/Abstract

摘要： 利用计算机辅助设计软件，研究了不同条件下28 nm体硅器件的单粒子瞬态（Single Event Transient，SET）效应，分析了不同器件间距、线性能量转移值和粒子入射角度对器件SET效应的影响。随着器件漏极间距的减小，SET脉冲幅度和脉冲宽度随之减小。与垂直入射的情况相比，倾角入射下SET脉冲幅度和宽度的减小程度更加明显，电荷共享效应更加显著。仿真结果表明，合理调节反相器相异节点的器件间距，利用器件间的电荷共享可以有效减弱重离子产生的SET脉冲，减少单粒子效应的反应截面。

Abstract: The single event transient (SET) effects of 28 nm bulk silicon devices under different conditions are studied using computer aided design software. The effects of device spacing, linear energy transfer value and particle incidence angle on the SET effects are analyzed. As the device drain spacing decreases, the SET pulse amplitude and pulse width decrease. Compared with the situation of vertical incidence, the decreases of the SET pulse amplitude and pulse width are more obvious at inclined incidence, and the charge sharing effect is more significant. The simulation results show that the reasonable adjustment of the device spacing of inverter dissimilar nodes and the use of charge sharing between devices can effectively attenuate the SET pulse generated by heavy ions and reduce the reaction cross section of single event effect.

Key words: single event transient, radiationeffect simulation, charge sharing
