| 摘 要： | 制备了大尺寸AlGaInP／GaAs SHBT和DHBT，对其直流特性进行了测试，并分析了AlGaInP／GaA。单异质结晶体管(SHBT)和双异质结晶体管(DHBT)的直流特性差异，深入研究了影响AlGaInP／GaAsHBT开启电压(Voffset)的各个因素。结果表明：AlGaInP／GaAsHBT开启电压与外加基极电流密切相关，采用宽发射区可大大降低器件的开启电压。

| Abstract: | Large- scale Heterojunction Bipolar Transistors were fabricated by using AlGaInP/GaAs HBT material grown by MOCVD. DC characteristics of AlGaInP/GaAs SHBT and AlGaInP/GaAs DHBT were studied. In addition, the collector- emitter offset voltages of AlGaInP/GaAs HBT were investigated, and several electrical factors affecting the offset voltage were discussed in detail. The results show that the collector- emitter offset voltages of AlGaInP/GaAs HBT are closely related to base current. And the collector- emitter offset voltage of AlGaInP/GaAs HBT can be decreased greatly by adopted wide emitter. |
