摘要
随着空间技术的发展,双极型器件和线性电路被广泛应用于辐射环境。从钝化层辐射损伤机理出发,介绍辐射诱生钝化层固定电荷与界面态的产生机理与计算模型,结合基极电流模型探讨双极型器件与电路的总剂量辐射效应,并针对双极型器件的低剂量率辐射损伤机理与模型展开讨论。
With the development of space technology , bipolar devices and linear circuits are widely used in the radiation environment .Based on the degradation mechanism of passivation layers , this paper reviews the gener-ation mechanism and physical model of radiation -induced fixed charge and interface state in the passivation layer.Incorporating the base current model , total dose radiation effects of bipolar devices and circuits are dis-cussed .In the last section , the enhanced low dose rate effects of bipolar devices are reviewed and analysis .
