GaN power devices are currently used in industrial and consumer applications, such as AC adapters and server power supplies. TSMC, a leader in sustainability and green manufacturing, supports GaN technology for its potential environmental benefits in automotive applications, such as on-board chargers and inverters for electric vehicles.
The partnership builds on ROHM and TSMC’s history of collaboration in the field of GaN power devices. In 2023, ROHM adopted TSMC’s 650V GaN high electron mobility transistors (HEMTs), a process increasingly used in consumer and industrial devices as part of ROHM’s EcoGaN™ series, including the 45W “C4 Duo” AC adapter (fast charger) produced by Innergie, a brand of Delta Electronics, Inc.
“GaN devices, capable of operating at high frequencies, are generating considerable excitement due to their potential contribution to miniaturization and energy savings, which can help achieve a decarbonized society. Having reliable partners is crucial for implementing these innovations in society, and we are delighted to collaborate with TSMC, which possesses world-leading, highly advanced manufacturing technology,” said Katsumi Azuma, Member of the Board of Directors and Senior Managing Executive Officer of ROHM. “In addition to this partnership, by providing user-friendly GaN solutions that include integrated control circuits to maximize GaN performance, we aim to promote the adoption of GaN in the automotive industry.”.
“As we advance with the next generations of our GaN process technology, TSMC and ROHM are expanding their partnership to include the development and production of GaN power devices for automotive applications,” said Chien-Hsin Lee, Senior Director of Specialty Technology Business Development at TSMC. “By combining TSMC’s expertise in semiconductor manufacturing with ROHM’s competence in power device design, we aim to push the boundaries of GaN technology and its implementation for electric vehicles.”.
