p—n结,对研究半导体的人特别是对制作半导体器件的人来讲,有着重要的意义。用作整流或电子计算机中的开关元件的二极管就是一个加了外引线的p—n结。可以起放大、振荡作用的结型晶体管和结型场效应晶体管是由互相靠近的两个p—n结组成的;其它如可控硅,一些光电器件等也是由p—n结构成的;因此,要制作半导体器件,就得设法形成符合要求的p—n结。现在形成p—n结的方法有合金烧结、热扩散、离子注入等。这些方法现在已有较成熟的工艺和相应的理论。目前扩散技术、离子注入技术已成为制作半导体器件的重要技术。是不是形成p—n结的方法就是这些呢?我们 The p-n junction is of great importance to those who study semiconductors, especially those who manufacture semiconductor devices. The diode used as a switching element in a rectifier or electronic computer is a p-n junction with an external lead added. Junction transistors and junction field effect transistors that can amplify and oscillate are made of two p-n junctions close to each other; others such as thyristors and some optoelectronic devices are also made of p-n structures; therefore , To make semiconductor devices, you have to try to form a compliant p-n junction. Now the formation of p-n junction method of alloy sintering, thermal diffusion, ion implantation. These methods now have more mature technology and the corresponding theory. At present diffusion technology, ion implantation technology has become an important technology for the production of semiconductor devices. Is not the way to form a p-n junction is that? We
