IBM researchers in Switzerland said they've come up with a patterning technique that lets them create structures as small as 15 nanometers. One nanometer is one billionth of a meter. One millimeter is equal to one thousandth of a meter. In comparison, a human hair is between .03 and .25 mm thick. Using the nanopatterning technique, the researchers have created a three-dimensional replica of the Matterhorn that's 25 nanometers high.   Using new techniques, IBM researchers have created models of the Matterhorn and the world's continents at incredibly small scales -- just over a dozen nanometers. The ability to manipulate matter accurately enough to sculpt models at this size could translate into new ways to create even smaller microchips. -(News Courtesy: Richard Adhikari)
