Before entering the cleanroom, the researcher dons special protective clothing to avoid carrying germs or other impurities into the highly sensitive environment. But it's not only people who have to conform to the strict hygiene requirements. Every item of equipment in the room, from lithography units to swivel chairs, must also comply with international guidelines.
Berkeley, CA - In a development that holds much promise for the future of solar cells made from nanocrystals, and the use of solar energy to produce clean and renewable liquid transportation fuels, researchers with the U.S.
Advances by the Rice University lab of James Tour have brought graphite's potential as a mass data storage medium a step closer to reality and created the potential for reprogrammable gate arrays that could bring about a revolution in integrated circuit logic design.
Pasadena, Calif. -- Scientists at the California Institute of Technology (Caltech) and IBM's Almaden Research Center have developed a new technique to orient and position self-assembled DNA shapes and patterns -- or "DNA origami" -- on surfaces that are compatible with today's semiconductor manufacturing equipment.
Berkeley -- Today's transistors and light emitting diodes (LED) are based on silicon and gallium arsenide semiconductors, which have fixed electronic and optical properties.
The unique properties of thin layers of graphite -- known as graphene -- make the material attractive for a wide range of potential electronic devices. Researchers have now experimentally demonstrated the potential for another graphene application: replacing copper for interconnects in future generations of integrated circuits.

A University of Colorado at Boulder team has developed a new method of shrinking the size of circuitry used in nanotechnology devices like computer chips and solar cells by using two separate colors of light.
COLLEGE PARK, Md. -- The ability to create tiny patterns is essential to the fabrication of computer chips and many other current and potential applications of nanotechnology. Yet, creating ever smaller features, through a widely-used process called photolithography, has required the use of ultraviolet light, which is difficult and expensive to work with.
Folding paper into shapes such as a crane or a butterfly is challenging enough for most people. Now imagine trying to fold something that's about a hundred times thinner than a human hair and then putting it to use as an electronic device.
The Defense Advanced Research Project Agency (DARPA) and Defense MicroElectronics Activity (DMEA) along with three University of California campuses have established a new Center for Nanoscience Innovation for Defense, to get university advances in the nanosciences into defense contractors' hands as soon as possible.
