十三、器件测试采用前述各步工艺制作一个半导体器件之后,如何知道它们质量的好坏呢?这就要通过对器件的电参数测试反映出来,器件的测试是器件制造中必不可少的很重要的一个步骤。随着半导体技术的发展,半导体器件的品种日益繁多,因此不可能在本节中对所有这些器件的电参数测试都一一说到。然而从所有半导体器件的使用角度来看,都不外乎放大(低噪声放大和功率放大等)、振荡和开关等主要应用,而晶体管在这些应用领域中都占有重要的地位,
13, the device test After using the above steps to produce a semiconductor device, how to know their quality is good or bad? This should be reflected by the electrical parameters of the device test, the device test is essential for device manufacturing is very An important step. With the development of semiconductor technology, the variety of semiconductor devices is becoming more and more numerous, so it is impossible to test the electrical parameters of all these devices in this section. However, from the perspective of the use of all semiconductor devices, it is no more than amplification (low noise amplification and power amplification, etc.), oscillation and switching and other major applications, and transistors in these applications occupy an important position,
