Hon Hai's research arm unveils AI-related technologies

Taipei, June 16 (CNA) Hon Hai Research Institute (HHRI), the research arm of Taiwan-based manufacturing giant Hon Hai Precision Industry Co., unveiled critical artificial intelligence server-related single-chip integrated circuit technology as well as high-performance power management solutions in early June in Japan, the company said Monday.

In a statement, iPhone assembler and AI server maker Hon Hai, also known as Foxconn globally, said these technologies have been recognized by the 37th International Symposium on Power Semiconductor Devices and ICs ISPSD or IEEE ISPSD 2025 held in Kumamoto from June 1-5.

Hon Hai said the single chip integrated circuit technology was jointly developed by HHRI's Semiconductor Research Center Director Kuo Hao-chung (郭浩中) and his colleague Hsiao Yi-kai (蕭逸楷), National Yang Ming Chiao Tung University associate professor Wu Tien-li (吳添立) and professor Chen Po-hung (陳柏宏) and National Central University associate professor Tu Chang-ching (杜長慶).

The single-chip integrated circuit technology, developed based on the silicon carbide process platform by Hon Hai's subsidiary Hon Young Semiconductor Co., is able to go beyond the performance attenuation limitations of traditional silicon-based circuits at high temperatures of more than 150 degrees Celsius, the world's largest contract electronics maker said.

Hon Hai said the latest single-chip integrated circuit technology is compatible with the existing silicon carbide component process and able to achieve more accurate analog signal processing in high-temperature environments, which is good for sensing and control systems functioning in extreme environments.

The recognized power management technology, Hon Hai said, is jointly developed by HHRI's semiconductor team and Chen's and Tu's research teams.

Their research efforts yielded to an LLC (inductor, capacitor, and capacitor) resonant converter controller by integrating Burst Mode control and Soft-Start functions, which can lower light load power consumption and improve system startup stability.

Hon Hai said a novel Burst Mode control solution for LLC resonant converters is aimed at achieving higher power efficiency and smaller output voltage ripple, while the new Soft-Start system can be started smoothly to avoid large current impact on components.

In recent years, Hon Hai has been aggressively diversifying its business under its "3 plus 3" strategy, focusing on electric vehicles, robotics, and digital healthcare. These efforts are driven by advancements in AI, semiconductors, and communication technologies.
