"NANOTECH: Precise placement of nanotubes demonstrated"

Growing carbon nanotubes on silicon chips could enable nanoscale transistors, but only if designers can specify exactly where the tiny devices grow. Now EEs at Cleveland's Case Western Reserve University have demonstrated how to grow nanotubes just precisely where you want them � self-aligned across a wafer and self-welded during growth. The Case Western EEs claim that their nanotube-enabled wafers merely need to be diced and the dice wire-bonded to a chip carrier. If that's indeed the case, the devices could be as reliable and cost-effective as current chips. "The nanotubes grow where you want them to grow � between two electrical posts," said Case Western EE and computer science professor Massood Tabib-Azar
