Transphorm and Fujitsu Semiconductor Announce the Start of Mass Production of Transphorm's GaN Power Devices

GOLETA, Calif., Jan. 26, 2015 /PRNewswire/ -- Transphorm Inc., Transphorm Japan Inc., and Fujitsu Semiconductor Limited announced today that Fujitsu Semiconductor group's CMOS-compatible, 150mm wafer fab in Aizu-Wakamatsu, Fukushima, Japan, has started mass production of Gallium Nitride (GaN) power devices for switching applications. The large-scale, automotive-qualified facility, which is providing exclusive GaN foundry services for Transphorm, will allow dramatic expansion of Transphorm's GaN power device business. This stepped up production can satisfy the increasing market demands for GaN devices, thereby enabling the next wave of compact, energy-efficient power conversion systems.

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

In 2013, Fujitsu Semiconductor and Transphorm announced the business integration of their GaN power device solutions. Since then, Transphorm's JEDEC-qualified process has been combined with Fujitsu Semiconductor's basic technology and ported to the CMOS-compatible, 150mm fab of Aizu Fujitsu Semiconductor Wafer Solution Limited, 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 of Fujitsu Semiconductor. "We will continue to enhance our high-quality manufacturing technology to support the stable supply of the products and bring the new 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 of Transphorm. "We will continue to expand our GaN power device portfolio with continued partnership with Fujitsu Semiconductor."
