1、技术发展史日本IC产品生产起始于六十年代的双极型IC产品.这类产品主要用于计算机和电子通讯等领域.六十年代中期后,开始生产MOS IC产品,早期产品是P沟的。六十年代后期,出现了N沟MOS产品,例如144位40ns NMOS RAM。推动MOSLSI发展的一种非常重要的应用是个人或台式计算器.七十年代初期,大约一半的IC国内市场是这些计算器.随着袖珍计算器的普及。IC产品市场显著增大。在七十年代,为满足市场需要和技术改善,主要IC产品逐渐地从双极型转向MOS型.计算器从台式转向带有液晶显示的袖珍型,极需功耗低的CMOS,因此,CMOS成为计算器业IC产品的主流,从而推动了CMOS VLSI产品的发展. 另一方面,日本IC制造商开始利用NMOS技术制造大容
1. History of Technology Development of IC Products in Japan The bipolar IC products started in the 1960s are mainly used in the fields of computers and electronic communications, etc. After the mid-1960s, MOS IC products started to be manufactured, and the early products were P groove. In the late 1960s, N-channel MOS products appeared, such as the 144-bit 40ns NMOS RAM. One of the most important applications driving the development of MOSLSI is personal or desktop calculators, and in the early seventies about half of IC’s domestic market was these calculators, with the advent of pocket calculators. IC product market has significantly increased. In the 1970s, in response to market needs and technological improvements, the major IC products gradually shifted from bipolar to MOS-type. The calculator shifted from desktop to pocket-sized LCD with extremely low power CMOS, so CMOS Became the mainstream of calculator IC products, thus promoting the development of CMOS VLSI products.On the other hand, Japanese IC manufacturers began to use NMOS technology to manufacture large capacity
