集成电路问世近二十年来,在提高电路性能、集成度和降低成本等方面都取得了显著的成绩.1978年,64KRAM的研制成功标志着集成电路技术发展到一个新阶段,即由大规模向超大规模过渡的新阶段.在VLSI的研制中,除继续对二十年来一直垄断集成电路领域的硅技术进行大力研究外,超导和砷化镓技术的研究工作也很活跃.虽然
In the past 20 years since the advent of integrated circuits, remarkable achievements have been made in improving circuit performance, integration and cost reduction, etc. In 1978, the successful development of 64KRAM marked the development of integrated circuit technology to a new stage, that is, In the VLSI development, in addition to continuing intensive research into silicon technologies that have monopolized integrated circuits for more than two decades, research into superconductivity and gallium arsenide technologies has also been very active.
