News   News : IBM builds world's smallest circuit
   posted by _Steve_ on 27-Oct-2002 14:28:57 (1502 reads)
Boffins at IBM have prototyped what is believed to be the world's smallest working computer circuits, using an innovative approach in which individual molecules move across an atomic surface like toppling dominoes.

The new "molecule cascade" technique enabled the scientists to make working digital-logic elements about 260,000 times smaller than those used in today's most advanced semiconductor chips, according to IBM.

The circuits were made by creating a precise pattern of carbon monoxide molecules on a copper surface. Moving a single molecule initiates a cascade of molecule motions, just as toppling a single domino can cause a large pattern to fall in sequence.

The scientists then designed and created tiny structures that demonstrated fundamental digital-logic building blocks (OR and AND functions, data storage and retrieval) and the "wiring" necessary to connect them into functioning computing circuitry.

The most complex circuit they built - a 12 x 17-nanometer three-input sorter - is so small that 190 billion could fit atop a standard pencil-top eraser. A nanometer is a billionth of a meter; or the length of five to 10 atoms in a line.

"This is a milestone in the quest for nanometer-scale computer circuitry," said Andreas Heinrich, a physicist at IBM's Almaden Research Center in San Jose, California, and one of the lead authors of the research article published in the online edition of Science Magazine, Science Express.

Posts like this amaze me. It's increadible how for technology has become. It's amazing to think things so small like this can be controlled and orginized. It mind blowing really.
