【摘要】 根据ＧａＡｓ阈值电压的测试原理，选取了一种比较精确的实验测试计算方法。在此基础上，分别设计了ＧａＡｓ 单晶阈值电压均匀件自动测试系统的硬件电路和软件程序，并利用此系统对ＧａＡｓ样品进行了实际测量，效果良好。更多还原

【Abstract】 According to the defining formula of GaAs threshold voltage, a kind of more accurate testing and calculating method is selected. We design the hardware and software of the auto-test system of the uniformity of GaAs threshold voltage based on that method. Finally, we measure the GaAs sample by the auto-test system, the effect is very good.更多还原
