Transphorm And Fujitsu To Integrate GaN Power Device Businesses

The companies will bring together technologies to accelerate market establishment and volume production of high-reliability, high-performance gallium nitride devices


Fujitsu, Fujitsu Semiconductor and Transphorm will integrate their GaN power devices for power supplies businesses.

This integration will dramatically improve the market competitiveness of Transphorm's GaN power device business. The three companies have also agreed that both Fujitsu and Fujitsu Semiconductor will take a minority equity position in Transphorm.

Device manufacturers around the world are competing to commercialise GaN power devices. While Transphorm has already released the first qualified high voltage commercial GaN devices, the company continues to make significant improvements in performance, quality and productivity.

Given this, Fujitsu, Fujitsu Semiconductor and Transphorm will bring together their complementary strengths in technology and manufacturing to enable superior GaN power device solutions to be delivered quickly to the market with both scale and affordability.

Transphorm's CEO Fumihide Esaka says, "Integrating Transphorm's operations with Fujitsu will enable high-volume and high-performance GaN power device production at Aizu-Wakamatsu, and we will also benefit from Fujitsu's strong technological capabilities underpinned by Fujitsu Groups' years of developments in the field of GaN power device."

Esaka continues, "In addition to being a future user for GaN solutions, Fujitsu has also built customer relationships with many power management companies in Japan, one of the most important markets for Transphorm. These complementary strengths will enable us to become the world leader in the GaN power conversion business and allow our customers to use our GaN power solutions with confidence."

Fujitsu's President Masami Yamamoto comments, "This business integration, together with our contribution to Transphorm's management as a minority shareholder, will enable Fujitsu to meet Transphorm's needs by offering low-cost volume production, highly reliable technologies, and quality assurance methodologies. This collaboration will greatly accelerate the introduction and market share expansion of Transphorm's GaN power devices."

Yamamoto adds, "While making efforts to promote the innovative value of more compact and exceptionally efficient power supply which only GaN technologies can provide, Fujitsu will aggressively work to embed GaN power devices into Fujitsu products as one component of our energy-saving solutions. Our work in the GaN RF device business continues to move forward, as does our drive to conduct advanced research on GaN devices and applied development of RF and power supply modules."

Fujitsu Semiconductor's President Haruki Okadaalso is also delighted with this move. He says, "From 2009, Fujitsu Semiconductor has moved forward on developing the mass production technology needed to bring GaN power devices to market, and at the end of 2011 began sample shipments of GaN power devices with 600 V breakdown voltage, followed by 150 V breakdown voltage GaN devices in July of this year. We have positioned GaN power devices as one of our future core products for the Aizu-Wakamatsu plant."

"The integration announced today will enable us to collaborate with Transphorm and leverage their technologies to accelerate the drive to mass production, and, we anticipate, contribute to the vitality of the Aizu-Wakamatsu region. With our track record and capabilities to mass produce silicon devices that meet the stringent quality requirements of customers in automotive, industrial equipment and other industries, the Aizu-Wakamatsu plant will also be able to offer GaN power devices that customers can purchase with confidence."

Fujitsu and Fujitsu Semiconductor will establish a new company in Japan for the GaN power device business, and will transfer to the new company their combined design and development assets as well as intellectual property rights in GaN power devices.

The two companies will make an in-kind investment in Transphorm in the form of the new company's shares, and will receive an equivalent value of shares in Transphorm in return. As a result of this transaction, the new company will become a wholly owned subsidiary of Transphorm.

In addition, Fujitsu and Fujitsu Semiconductor will make a cash investment in Transphorm and will contribute to Transphorm's management in their roles as minority shareholders. The employees at Fujitsu and Fujitsu Semiconductor who are directly involved in the GaN power device business will be reassigned to the new company, where they will continue development and production work with Transphorm's employees.

After the integration, Transphorm will continue R&D work at both its prototyping line in the US as well as Fujitsu Semiconductor's Aizu-Wakamatsu plant, which will be under exclusive contract with Transphorm to handle wafer processing. Transphorm and Fujitsu Semiconductor intend to build a global market by generating synergies from bringing together their marketing, customer support, and applications development capabilities.

 



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
