Novel CU-Boulder technique shrinks size of nanotechnology circuitry
Date:4/16/2009

ocused in one place, it inscribed a small solid dot. If the beam was moving the focus through the material, it created a thin thread, or line.

The researchers then added a second ultraviolet laser focused into a halo, or donut, which surrounded the blue light. The special monomer formulation was designed to be inhibited by the UV light, shutting down its transformation from a liquid to a solid, he said. This "halo of inhibition" prevented the edges of the spot or line from developing, resulting in a much finer final structure.

The process may be another step in "Moore's Law," a trend described by Intel co-founder George Moore in 1965, which predicted that the number of transistors that can be placed on a single integrated circuit doubles about every 18 months. Since the technology industry is driven by Moore's Law, a stall in such advances would cause huge shockwaves for companies that make chips to power up devices like digital cameras, Blackberries and iPods even as they shrink them.

The new technology has the potential to lead to the construction of a variety of nanotechnology devices, including "nanomotors," said McLeod. "We now have a set of new tools. We believe this is a new way to do nanotechnology."
