JEDEC To Set Standards For Wide Bandgap Semiconductors

News

JC-70 Wide Bandgap Power Electronic Conversion Semiconductors committee will focus on GaN and SiC device reliability, qualification, characterisation and testing methods

JEDEC Solid State Technology Association, thel standards development organisation, has formed a new JEDEC committee: JC-70 Wide Bandgap Power Electronic Conversion Semiconductors.

Led by interim chairs from Infineon, Texas Instruments, and Wolfspeed, a Cree Company, the new JC-70 committee will initially have two subcommittees: GaN and SiC and focus on Reliability and Qualification Procedures; Datasheet Elements and Parameters; and Test and Characterisation Methods.

JC-70's first committee meeting will be co-located with the 5th IEEE Workshop on Wide Bandgap Power Devices and Applications (WiPDA), on October 30, 2017 in Albuquerque, NM. JEDEC meetings are open to committee members and invited guests only, and interested companies worldwide are welcome to join JEDEC to participate in this important standardization effort.

"The formation of the JC-70 committee is part of an ongoing effort within JEDEC to extend our standards setting expertise to new technologies to meet market demands. We welcome all interested companies to participate in the development of open industry standards within JEDEC."

SiC and GaN are the most mature wide bandgap (WBG) power semiconductor materials and offer immense potential for enabling higher performance, more compact, and energy efficient power systems. "WBG GaN and SiC technologies are poised to benefit from the development of standards focused on quality and reliability, datasheets, and test methods," said Tim McDonald, senior director, GaN applications and marketing at Infineon Technologies.

During an industry conference in the spring of 2016, a working group of industry experts was formed. Designated as GaNSPEC DWG, it began laying the necessary groundwork for the development of standards for GaN. JEDEC began providing logistical support to the group shortly thereafter.

"To meet the demand of today's energy and product requirements, this team is helping to create the mature industry infrastructure that customers need to design power supplies," said Stephanie Watts Butler, technology innovation architect at Texas Instruments. "The broad academic and industry participation is indicative of the importance of wide bandgap for complying with these requirements."

GaNSPEC DWG was soon joined by a counterpart: the SiCSPEC working group. The two groups grew to almost 50 device manufacturers, equipment manufacturers, technology creators, academic representatives, and government labs from the US, Europe, and Asia. "Our consensus is that JEDEC is the logical home for the continuation of these efforts in a public forum, and the team is delighted to invite industry participation in this new JEDEC committee," said Jeff Casady, business development & programs manager from Wolfspeed, a Cree Company. "Creating clear, universal standards is a key step in advancing the adoption of wide bandgap technologies. These new parameters will enable users to design SiC and GaN devices into the systems of tomorrow, thus creating a more energy efficient future."

John Kelly, JEDEC President, added, "The formation of the JC-70 committee is part of an ongoing effort within JEDEC to extend our standards setting expertise to new technologies to meet market demands. We welcome all interested companies to participate in the development of open industry standards within JEDEC."



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.
