Microelectronics and Nanotechnology

Microelectronics and nanotechnology are closely related fields that investigate the properties—electrical and others—of the very small. Although their names suggest the difference in scale between a micron (a millionth of a meter) and a nanometer (a billionth of a meter), in fact a particular feature can as easily be described as .08 microns or 80 nanometers long. The word nanotechnology was first used in 1974, but by then scientists had long been working with entities smaller than a nanometer, including films just one molecule thick.
