Tokyo Bulletin No.121［Jan 31, 2020］”High Electron Mobility Transistor, HEMT”
IEEE Milestone Dedication Ceremony and Commemorative Lectures(The 11th Lecture Meeting of Tokyo Section in 2019) Taking Place●IEEE Milestone Dedication Ceremony
The “High Electron Mobility Transistor, HEMT”, invented in 1979 was certified asIEEE milestone. The dedication ceremony for IEEE milestone was held on December
18, 2019 at Empire Hotel Tokyo. Dr. Toshio Fukuda, IEEE President-Elect, Professorof Meijo University, presented the plaque to Dr. Hirotaka Hara, CEO andRepresentative Director of Fujitsu Laboratories Ltd. The HEMT was the 35th IEEE
milestone in Japan.
Achievement on the plaque is as follows.
・High Electron Mobility Transistor, HEMT, 1979
“The HEMT, invented in 1979, was the first transistor to incorporate an interface
between two semiconductor materials with different energy gaps. HEMT proved
superior to previous transistor technologies due to high mobility of channel carriers,
resulting in high speed and high frequency performance. HEMTs have been widelyused in radio telescopes, satellite broadcasting receivers and cellular base stations,giving rise to a fundamental technology supporting the information andcommunication society.”
A presentation ceremony hosted by IEEE Tokyo Section was held at Hikari-no-ma,
Imperial Hotel Tokyo. There were 66 attendees. The master of ceremonies was Dr.
Yasuhiro Takishima, Secretary of IEEE Tokyo Section, Executive Director of KDDI
Research, Inc. First on the agenda, Dr. Hideyuki Tokuda, Chair of IEEE Tokyo Section,
President of National Institute of Information and Communications Technology, gavea speech as an organizer, followed by Dr. Toshio Fukuda. Next, a plaque waspresented by Dr. Toshio Fukuda to Dr. Hirotaka Hara. Dr. Hirotaka Hara gave aspeech on behalf of the plaque recipient. After the presentation ceremony, Dr.
Hideyuki Tokuda handed a letter of thanks to Dr. Naoki Hara, Senior Expert at Fujitsu
Laboratories, Ltd. The plaque is put on display in their Laboratory in Atsugi,Kanagawa.
