一、前言纵观半导体技术的发展史,从48年晶体管的问世,58年集成电路的出现,68年大规模集成电路的诞生,到78年末揭开了超大规模集成电路的序幕,至今已进入了第四代产品。历经卅年时间,其发展速度,大约是每十年更新一代产品。电路的集成度若从64年开始估算,平均每年大约提高一倍。78年进入超大规模集成电路领域后,预计其集成度,将是每四年提高四倍。80年的水平,仅以256K位动态RAM和64K位静态RAM为例,其集成度均已达到50—60万元件/片。估计84年前后可能实现0.5—1兆位的动态存
I. Foreword Throughout the development history of semiconductor technology, from the advent of 48-year transistor technology, the emergence of 58-year integrated circuits and the birth of 68-year large-scale integrated circuits, the prelude of ultra-large-scale integrated circuits was opened at the end of 78 and has been entered The fourth generation of products. After a long time, its development rate is about every 10 years to update a generation of products. If the degree of integration of the circuit is estimated from 64 years, the average annual doubled. After 78 years into the field of VLSI, it is expected that its integration will quadruple every four years. The level of 80 years, only 256K-bit dynamic RAM and 64K-bit static RAM, for example, the integration has reached 50-60 million components / piece. It is estimated that a dynamic memory of 0.5-1 megabit may be realized around 1984
