不同剂量率下NPN管和NMOSFET管的电离辐照效应
The Ionizing Radiation Respon ses of NPN Transistor and NMOSFET at Different Dose-rates
【摘要】 研究了 NPN双极晶体管和 NMOSFET在不同剂量率环境下的电离辐照效应。研究表明 ,NPN管在低剂量率辐照下 ,电流增益衰降更为显著 ,且具有真正的剂量率效应 ;而 NMOS管在低剂量率辐照下产生的阈电压负向漂移比高剂量率辐照时小 ,其辐照效应是时间相关效应 ,而非真正的剂量率效应。
【Abstract】 The ionizing radi ation responses of NPN bipolar transisto r and NMOSFET at different dose-rates ha ve been investigated. The results have s hown that the current gain degradation o f NPN transistor is larger at low dose-r ates than at high dose-rates, and the ef fect is a true dose rate effect, but the threshold voltage of NMOSFET has more s hift at high dose-rates, and it is a tim e dependent effect.
