美国《科学》杂志评出2001年十大科学成就,第一项就是纳米电子学的突破。纳米技术是由微电子学的发展而提出的。当前,电子计算机的水平以其芯片(集成电路)衡量,每块芯片面积不到一张邮票的大小,上面集成晶体管(半导体管)不下4000万个,连线宽度只130纳米(0.13微米,一纳米为十亿分之一米)。芯片工程师预言,10年内每个晶体管可缩小到120微米见方,但即使如此,它还比分子大6万倍。在1974年超大规模集成电路开始迅速发展的时候,两位
The United States “Science” magazine named the 2001 top ten scientific achievements, the first is a breakthrough in nanoelectronics. Nanotechnology is proposed by the development of microelectronics. Currently, the level of electronic computers, measured in terms of their chips, is less than one stamp per chip, with less than 40 million integrated transistors (semiconductors) and a connection width of only 130 nanometers (0.13 micrometres, one Nanometer is one billionth of a meter). Chip engineers predict that within 10 years each transistor can be reduced to 120 microns square, but even so, it is also 60,000 times larger than the molecule. In 1974 when the VLSI began to rapidly develop, two
