IBM creates new generation of microprocessor technology

Scientists at IBM have formed another to silicon for the logic gates on microchips that will make sure the continuing reduction of the vital digital switching mechanism for at least ten more years.
The IBM breakthrough, first reported in Nature Nanotechnology & by the New York Times, uses carbon annotates a kind of molecule that is a substitute to silicon for the making of miniature logic gates in microprocessors.

Researchers at IBM’s T.J. Watson Research Center  in Yorktown Heights, N.Y. have formed a pattern of carbon nanotubes on the surface of a silicon wafer. The nanotubes utilized to produce the processors, the report said, are hybrids of silicon & carbon nano tubes with more than ten thousand working transistors.
Basically carbon nanotubes are solitary sheets of carbon rolled into a cylindrical form. 

IBM Certification

In the Nature Nanotechnology paper, the IBM researchers explained how they were clever to place ultra-small rectangles of the stuff in usual arrays by placing them in a soapy combination that creates them soluble in water.

The scientists utilized a procedure explained as “chemical self-assembly” to generate the decorative array in which the nanotubes stick in various areas of the surface while other areas are left untouched. That growth allows them to organize the nanotubes hundred times more thickly than earlier methods, and necessary step in economical chip developed.
