| 中文摘要 | 空间电磁脉冲注入硅双极型晶体管后可能会导致晶体管烧毁。借助2维数值仿真和理论分析研究了基极注入短电磁脉冲对双极型晶体管的作用,得出结论:晶体管的热斑位于基极边缘,由于该点既是电场峰所在,又是电流最密集之处,热量产生集中,因此基极注入脉冲使晶体管烧毁所需的能量比其它两电极注入要少;在基极注入短脉冲作用下,晶体管烧毁所需能量几乎不随脉冲宽度变化;烧毁所需脉冲功率近似与脉冲宽度成反比。; Bipolar junction transistors may be burned out by injected electromagnetic pulse.The effects of electromagnetic pulse injected from base on bipolar junction transistor were studied with 2-dimensional simulation.Results show that the hot spot locates on the edge of base electrode due to the distribution of current density and electric field.The energy needed for burnout is the smallest when pulses are injected from base among the three electrodes for the heat generation is centralized at that point.If the pulse width is short,the energy needed for burnout nearly remains constant while the pulse power needed is approximately in inverse proportion to the pulse width.; 国家863计划项目资助课题 |
