Rohm licenses TSMC production technology for GaN semiconductors

Rohm has decided to combine its own development and manufacturing technologies for GaN power devices with TSMC’s process technology in order to establish a comprehensive production system. By licensing TSMC GaN technology, ROHM will strengthen its supply capability to meet growing demand for GaN in applications such as AI servers and electric vehicles. TSMC’s 650-volt process technology will be transferred to Rohm’s Hamamatsu facility. Rohm plans to complete the production facility by 2027 to meet rising demand. In late 2024, the two companies announced a partnership in the field of ‘automotive GaN.’ Upon completion of the technology transfer, ROHM and TSMC will amicably conclude their automotive GaN partnership. At the same time, the two companies will continue to strengthen collaboration for higher efficiency and more compact power supply systems.
