美国电脑业巨擘 IBM 公司再创新绩,成功地开发出—种全新的半导体制造技术。这种全新的半导体制造技术的开发,将使芯片生产发生重大变化,更先进的铜质芯片将取代传统的铝质芯片。这项被称为 CMOS 7S 的半导体制造新技术,最大的改进是利用铜质取代铝质作为芯片的电路导体(金属丝),从而为半导体制造技术树立了新的里程碑。众所周知,虽然铜质在很久以前就已被电子业界公认为优良的电路导体,但由于芯片中的硅与铜同时使用,就会产生排斥作用。这就使采用铜质生产芯片,会遇到不少困难。因此,电子业界只能采用质素较次的铝质来生产 IBM, the US computer giant, has made new achievements and successfully developed a new kind of semiconductor manufacturing technology. The development of this new semiconductor manufacturing technology will lead to major changes in chip production, and the more advanced copper chips will replace traditional aluminum chips. Known as CMOS 7S, a new technology in semiconductor manufacturing, the biggest improvement is the use of copper instead of aluminum as a chip circuit conductor (wire), which sets a new milestone in semiconductor manufacturing technology. It is well known that although copper has long been recognized by the electronics industry as an excellent circuit conductor, copper is repelled by the simultaneous use of silicon and copper in the chip. This makes the use of copper production chips, will encounter many difficulties. Therefore, the electronics industry can only produce aluminum with inferior quality
