近三十年内,半导体异军突起,成为发展现代电子技术必不可少的东西。半导体器件具有体积小、重量轻、耗电省、可靠性高等优点,在当前工业生产、军事技术和科学实验中都已经广泛地用半导体晶体管来代替电子管。第一个半导体晶体管是从哪里来的呢?从天上掉下来的吗?不是!它出现在二十世 Nearly thirty years, the sudden emergence of semiconductors, has become an essential part of the development of modern electronic technology. Semiconductor devices with small size, light weight, low power consumption, high reliability, in the current industrial production, military technology and scientific experiments have been widely used semiconductor transistors to replace the tube. Where did the first semiconductor transistor come from? Did it fall from the sky? No! It appeared in XX
