Fujitsu Honored with IEEE Milestone for High Electron Mobility Transistor

Fujitsu Laboratories Ltd.

Kawasaki, Japan, December 18, 2019

The high electron mobility transistor (HEMT) developed by Fujitsu Laboratories has been certified as an IEEE milestone. The technology was developed by the company in 1979 and was recognized for its innovative achievements in improving the performance of radio telescopes and satellite broadcasting receivers.

Fujitsu was awarded with the IEEE Milestone plaque at a ceremony held on December 18 in Tokyo, Japan.

About IEEE and IEEE Milestones

With over 420,000 members in more than 160 countries, the Institute of Electrical and Electronics Engineers (IEEE) is the world's largest technical professional society in such fields as electricity, electronics, information and telecommunications. The IEEE Milestone has recognized historic achievements in these areas that have successfully contributed to the development of local communities and industries over the past 25 years.

About HEMT

The HEMT is a newly structured transistor that can operate at high speed by creating a two-layer structure that spatially separates the source and travel regions of electrons within the transistor. This feature enables the transistor to receive weak, high-frequency signals with high sensitivity. In 1985, Fujitsu commercialized the HEMT as a microwave semiconductor device product with the world's lowest noise level and it was adopted for the radio telescope at the Nobeyama Radio Observatory (NRO) in Nagano, Japan. The telescope discovered an unknown interstellar molecule one year later in 1986, significantly contributing to the progress of basic science. After being installed in satellite broadcasting receivers around the world, the transistors have become an essential part of various microwave and millimeter-wave devices, such as mobile devices, base stations, GPS receivers, and millimeter-wave radar that prevents collisions between automobiles. Accordingly, the HEMT has been the fundamental technology supporting the information and communications society.
