Nanolithography could be used for circuits, medical diagnostics
Abstract:
Nanolithography, the process of carving circuits into computer chips far smaller than the electronic components currently embedded in digital devices, could produce faster, more powerful processors. Unfortunately, every process of nanolithography remains too expensive and too slow for commercial applications.
Enter beam-pen nanolithography. By using tiny beams of light, this method offers a means to rapidly and inexpensively make and prototype circuits, optoelectronics and medical diagnostics, doing for nanofabrication what the desktop printer has done for printing.
"It's all about miniaturization," said Chad Mirkin, director of Northwestern University's International Institute for Nanotechnology. "Rapid and large-scale transfer of information drives the world. But conventional micro- and nanofabrication tools for making structures are very expensive. We are trying to change that with this new approach to photolithography and nanopatterning."
