IBM sees future of microchips in DNA

IBM said it was looking to DNA "origami" for a powerful new generation of ultra-tiny microchips.

The US computer giant collaborated with California Institute of Technology researchers to develop a way to design microchips that mimic how chains of DNA molecules fold, allowing for processors far smaller and denser than any seen today.

"This is a way to assemble an electronics device of the future," said Bill Hinsberg, manager of the lithography group at IBM's Almaden Research Center in California, on Monday.

"It offers a potential way to construct nano-scale devices. The industry has always gone in the direction of making things smaller, because that opens the realm of possibilities."

A tenet of the chip industry is Moore's Law, a history-backed belief that the number of transistors that can be placed on a computer circuit doubles every two years, enabling smaller but increasingly powerful computing devices.

Lithography is a common method of making computer chips that have shrunk to contain technology measuring a mere 22 nanometers. The "DNA origami" method can allow for chip features as slight as 6 nanometers, according to IBM.

"At some point, it gets more difficult to get smaller," Barnett said. "We've pursued DNA origami as a way to assemble an electronic device of the future."
