摘要
对单台面SiGeHBT在E-B结反偏应力下直流特性的可靠性进行了研究。研究结果表明,随应力时间的增加,开启电压增加,直流电流增益下降,特别是在低E-B正偏电压时下降明显;而交流电流增益退化缓慢。
The reliability in DC characteristics of single-mesa SiGe HBT is investigated under reverse emitter-base stress due to hot holes.The results show that as the stress time increase,turn-on voltage increase,DC current gain decrease,particularly at low forward base-emitter bias.However,AC current gain degrade slowly.
