ELuminating: company innovates chip technology
Walter E., CTO of ELume, holds a 300 mm wafer with custom multiple coatings applied by spin technology improving high speed semiconductors, and like devices.
The chief technical officer of ELume, Southern California microchip foundry, rifles through a tray of glass and silicon wafers etched with microscopic electronics. A molecular sieve, reusable biosensor chips, hundreds of thousands of microscopic mirrors for flat panel projection displays--each represents months of work and a good measure of fun for the six-employee company.
"You want to see poetry in motion, I’ll show it to you," said Walter E., positioning a finely etched wafer under a microscope. "I can look at it a million times and never get tired of it," he added later. "It’s a city... It’s a living world if you can become an electron for a moment" and mentally traverse the microscopic paths.
ELume does process development and short runs of... [Read more]
Newly discovered properties of bismuth telluride hold promise for spintronic quantum computing. Bismuth Telluride Valley doesn't quite have the same ring to it, but a new discovery may mean the end of silicon chips. After decades of using Bi2Te3 for its thermoelectric properties, researchers have discovered new properties of the material that paves the way for bismuth telluride chips constructed to power quantum computers.
Writing in Science Express, researchers from SLAC National Accelerator Laboratory and Stanford University detail how they created a new form of bismuth telluride that allows electrons on the surface of the material to act like photons, travel with no loss of energy, and maintain specific spins for an indefinite period of time. Those properties make the new form of bismuth telluride an ideal semiconductor for quantum computer chips.
"This material has three unique properties," said Yulin Chen, a Stanford physicist and co-author of the... [Read more]
IBM Research and Caltech have announced a breakthrough that could lead to powerful but tiny computer chips, using DNA. The self-assembling origami structures could reduce chip production costs and resolve key semiconductor challenges as chip sizes drop below 22nm. The IBM and Caltech breakthrough with DNA appears to go beyond Moore's law.
Research and the California Institute of Technology on Monday announced a scientific advancement that could make way for the semiconductor industry to build more powerful, faster, tinier, more energy-efficient computer chips. The breakthrough draws from lessons scientists have learned from DNA.
Together with Caltech's Paul W.K. Rothemund, IBM researchers reported an advancement in combining lithographic patterning with self-assembly. This method of arranging DNA origami structures on surfaces compatible with today's semiconductor manufacturing equipment could reduce... [Read more]
