30.08. 2017 Semiconductor Technology News - Semiconductor News, Semiconductors, Semiconductor Technology

In the Moore's Law race to keep improving computer performance, the IT industry has turned upward, stacking chips like nano-sized 3-D skyscrapers. But those stacks, like the law it's challenging, have their limits, due to overheating. So, our team in New York, alongside colleagues in Zurich, received a 2013 contract to tackle intra-chip cooling from the Defense Advanced Research Projects Agency (DARPA) in its ICECool program. For our part, we developed a new cooling technology to overcome the thermal barrier of stacking chips, an on-chip solution that could help to even cool off entire datacenters.

World’s highest output density with power amplifier for W-band GaN transmitters

24.07. 2017 Semiconductor Technology News - Semiconductor News, Semiconductors, Semiconductor Technology

Fujitsu today announced the development of a gallium-nitride (GaN) high-electron mobility transistor (HEMT) power amplifier for use in W-band (75-110 GHz) transmissions. To realize long-distance, high-capacity wireless communications, a promising approach is to utilize the W-band and other high frequency bands that encompass a broad range of usable frequencies, and increase output with a transmission power amplifier. At the same time, demand exists for improved efficiency in power amplifiers in order to mitigate the increased power consumption of communication systems. Fujitsu has now succeeded in developing a power amplifier for use in W-band transmissions that offers both high output power and high efficiency, improving transistor performance through the reduction of electrical current leakage and internal GaN-HEMT resistance.
