1972年美国半导体工业产值达到16.5亿美元,比1971年增长13％;其中MOS集成电路发展最快,只是数字双极集成电路稍有下降,线性电路也提高25％,光电器件增加40％,分立元件也有所增加。一、MOS MOS现已成为TTL新的竞争者(70年产值为2百万美元),MOS已很快成为标准产品工业的竞争者。今年将是从常规产品转为标准产品的一年。这一方面意味着MOS工艺日臻完善,另一方面表明将大幅度降价,约在1975年标准产品可占MOS总 In 1972, the output value of the semiconductor industry in the United States reached 1.65 billion U.S. dollars, an increase of 13% over 1971. MOS integrated circuits were the fastest growing among them, with only a slight dip in the number of bipolar integrated circuits, a 25% increase in linear circuits and a 40% increase in optoelectronic devices. Components have also increased. First, MOS MOS is now a new competitor to TTL ($ 70 million in 70-year output) and MOS has quickly become a competitor to the standard product industry. This year will be a year from standard products to standard ones. This means that MOS technology is improving on the one hand, on the other hand shows that it will substantially lower prices, about standard products in 1975 can account for MOS total
