集成电路出现以来的20多年历史中,集成电路工业兴旺发达的形象一直给人们以深刻的印响.1985年曾出现集成电路工业萧条的形势,然而,即使面临这种困难,集成电路技术进展的速度并没受到很大影响,超大规模集成电路系统的复杂性仍以前所未有的速度增长着. 今天,超大规模集成电路品种日新月异变化的现状离不开工艺与制造水平的提高。另外,还有两个重要因幸,即一是过去进行电子线路与计算机系统的设计者们,现在大量转
In the more than 20 years since the advent of integrated circuits, the image of a thriving integrated circuit industry has been deeply imprinted. In 1985, there was a situation of recession in the integrated circuit industry. However, despite such difficulties, advances in integrated circuit technology Speed has not been greatly affected, the complexity of VLSI system is still growing at an unprecedented rate.Nowadays, the status quo of the rapid development of VLSI variety is inseparable from the improvement of technology and manufacturing level. There are two other important reasons for this. First, designers who used to carry out electronic circuits and computer systems have turned a lot in the past
