Process melds nanowires and chips

  May 12/19, 2008
Cross a standard chipmaking technique with recently-developed ways of manufacturing nanowire circuitry and you have a way to mass-produce the tiniest of electronic devices. Spin-on glass puts a uniform thin layer of insulating glass between a silicon chip and metal electrodes. Use spin-on glass with techniques to place nanowires on a silicon surface, and you've got thousands of tiny, closely spaced light-emitting diodes or other devices on a chip.
