GaN power device mass production ramped up in Japan

Transphorm has established the industry’s first and only qualified 600V GaN device platform, backed by its GaN power IP portfolio. The world’s first PV power conditioner products using Transphorm's GaN module was launched in January 2015. Other applications include small AC adapters, high-density power supplies for PCs, servers and telecomms and efficient motion control systems.

In 2013, Fujitsu and Transphorm announced the business integration of their GaN power device solutions. Since then, Transphorm’s JEDEC-qualified process has been combined with Fujitsu’s basic technology and ported to the CMOS-compatible, 150mm fab at Aizu Fujitsu, with key improvements for high-volume, silicon-compatible device manufacturing. Understanding that a highly reliable manufacturing production line is one of the essential requirements of any business expansion, the companies have successfully finished the development in Aizu-Wakamatsu and have now started mass production.

“The start of the mass production in a CMOS-compatible fab is a significant step forward toward achieving the widespread use of GaN power devices, as well as a demonstration of the successful integration of both companies’ strengths,” said Haruki Okada, President, Fujitsu Semiconductor. “We will continue to enhance our high-quality manufacturing technology to support the stable supply of the products and bring the value of GaN power devices to the world.”

“Manufacturing Transphorm’s GaN power devices at the Fujitsu Aizu-Wakamatsu facility will assure our customers a scalable, stable supply of products with the stamp of Fujitsu’s proven, high-quality standard in mass manufacturing,” said Fumihide Esaka, CEO, Transphorm. “We will continue to expand our GaN power device portfolio with continued partnership with Fujitsu Semiconductor.”
