一、历史的简要回顾日本从1950年左右,开始着手试制半导体。由于那时日本还没有医治好战争的创伤,加之国内自然资源的贫穷及缺乏必要的实验设备和手段,不得不从美国进口半导体,但多半都失去了效用。由于自然环境潮湿,从美国进口的半导体到了研究室多半都不能用。所以,在初期阶段,用进口器件进行研制遭受挫折,与此同时从美国引进半导体生产技术也并不是一 I. A brief historical review Japan began experimenting with semiconductors from around 1950. Since Japan had not yet healed the wounds of war, coupled with the poverty of domestic natural resources and the lack of necessary experimental equipment and means, it had to import semiconductors from the United States, but most of them lost their usefulness. Due to the damp natural environment, most semiconductors imported from the United States cannot be used in research laboratories. Therefore, at the initial stage, the development of imported devices was frustrated. At the same time, the introduction of semiconductor production technology from the United States is not a
