Refining Semiconductors, One Atom at a Time

Abstract:
At the heart of semiconductor fabrication are crucial additives called dopants. These impurities change the electronic properties of silicon or other material to make the transistors and other components of a chip. Currently these dopants are added in bulk, their exact location usually no more a problem than the exact location of grains of baking soda or raisins stirred into cake batter. But a physicist has succeeded in controlling doping precisely at the atomic level. Michael F. Crommie, a professor of physics of the University of California at Berkeley, has attached single dopant atoms, one by one, to single molecules, thereby custom-tailoring their electronic properties.
