摘要
分析了AlGaAs/GaAsHBT的原理和材料结构,详细介绍了AlGaAs/GaAsHBT的器件结构及工艺流程,并对两方面进行了优化,研制出了特性较好的AlGaAs/GaAsHBT,其电流放大系数达到180,是目前国内报道的最高水平;开启电压小于0.3V.
The theory and material structure of AlGaAs/GaAs Heterojunction Bipolar Transistor (HBT) are analyzed. The device structure and the pivotal process of it are introduced in detail. An optimized AlGaAs/GaAs HBT was made, which had good characteristics, high current gain (β) of 180 and low turn-on voltage of less than 0.3 V. It was the best result of current gain reported before in China.
