This 10 x 10 mm wafer uses Group4 Labs' own technology to atomically attach a single gallium nitride layer to a 25-micron-thick synthetic diamond substrate. The exterior has an atomically smooth finish with a gallium-facing surface that is epi-ready for further epitaxial deposition. It comes freestanding or on a disposable silicon wafer mount. It uses the sub-nanometer proximity of the chip's active region to the diamond to extract heat from the chip's core almost the very instant it is generated, lowering heat build-up during high-power and high-speed transistor applications. The diamond's thermal conductivity is about 3-30 times more than ordinary semiconductors, boosting a transistor array's power-density by at least 10-100 times. It sells for $500-$600 per unit based on quantity. Group4 Labs LLChttp://rbi.ims.ca/4928-637
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
