Chinese Scientist Yu Faxin Detained by Anti-Graft Authorities in Hubei

Leading Scientist Detained

Yu Faxin, a top Chinese scientist known for his work in developing semiconductor chips for military weapon systems, has been detained by anti-corruption authorities in Huangshi, Hubei province. His company, Zhejiang Great Microwave Technology, a Shanghai-listed firm, confirmed on Monday, September 23, that it had learned of his detention on September 21 from his family. The specific charges against Yu have not been publicly released by the Supervisory Commission of Huangshi.

Background and Expertise

Yu Faxin holds significant positions as the actual controller and chairman of Zhejiang Great Microwave Technology, and is also a Qiushi distinguished professor at Zhejiang University's School of Aeronautics and Astronautics in Hangzhou. He is recognized as an expert in microwave and millimetre-wave radio frequency technology, having made advancements in communication, navigation, and radar technologies. His research also encompasses process technology for semiconductor materials, including gallium nitride and gallium arsenide compounds.

His company, founded in 2015 and listed on Shanghai's Nasdaq-style tech board, the Star Market, in 2022, is a key supplier of advanced components. According to its 2024 annual report, Zhejiang Great Microwave Technology provides:

• Radio frequency transceivers and chips for wireless communication
• Power management integrated circuits for satellite communication and space target monitoring radar
• Microsystems for data links

The company has stated that its chips are widely utilized in military equipment, with some products even showcased during the 70th National Day military parade in 2019.

Context of China's Anti-Corruption Drive

The detention of Yu Faxin occurs within the broader context of China's ongoing anti-corruption campaign, which has intensified under President Xi Jinping since 2012. This campaign has targeted various sectors, including the military and, more recently, the high-tech and chip industries. Authorities aim to ensure that the country's scientific and technological development progresses 'in the right direction' and to combat issues such as bribery and the embezzlement of research funds.

While the supervisory commission has not issued a statement regarding Yu's case, Zhejiang Great Microwave Technology has assured that company operations will continue as normal, with other directors and senior management fulfilling their duties.
