Cree Earns US DoD Manufacturing Readiness Level 8

Designation for GaN on SiC Radar/Electronic Warfare MMIC production

Cree has earned US Department of Defense (DoD) manufacturing readiness level eight (MRL 8) for production of GaN monolithic microwave integrated circuits (MMICs).

This designation verifies Cree's ability to provide assured, affordable and commercially viable production capabilities and capacities for items essential to national defense. The designation was granted upon Cree's successful completion of the DoD's Defense Production Act (DPA) Title III Gallium Nitride on Silicon Carbide Production Capacity Program.

"We are pleased to have been allowed to participate in the DPA Title III Program and are honored to have subsequently earned MRL 8 designation"

"Cree exemplifies the mission-ready capability of a company that the DPA Title III office seeks," said Mark Buffler, director, Defense Production Act Title III Program within the Office of the Secretary of Defense. "The key objective of these public-private partnerships is the creation of assured, affordable and commercially viable production capabilities and capacities for products and materials essential for our national defense while strengthening the economic and technological competitiveness of the U.S. defense industrial base."

Led by an integrated program team (IPT) and jointly funded through a public-private partnership effort, the three-year, multi-phase GaN on Silicon Carbide Radar/Electronic Warfare MMIC Production Capacity Project was structured to assess and refine manufacturing processes necessary to support a full-rate MMIC production capability.

The IPT comprised the Air Force Research Laboratory Materials and Manufacturing Directorate (AFRL/RX) personnel, Cree engineers and manufacturing experts and select government consultants. The program was managed by the Deputy Assistant Secretary of Defense, Manufacturing and Industrial Base Policy (MIBP) and administered by the US. Air Force, the executive agent within the DoD. Funded with $18 million in direct government funds and $3.5 million in Cree funds, the national defense program accounted for a total public-private partnership effort of $21.5 million.

Since 2010, Cree has shipped more than five million MMICs and devices, making it one of the largest US  suppliers of advanced GaN technology for both the DoD and commercial markets. During this time, approximately four billion device hours in the field have been accumulated with an associated, industry-leading FIT rate of less than 10 failures per one billion device hours, which validates the outstanding robustness of Cree's manufacturing process and resultant devices under fielded conditions.

"We are pleased to have been allowed to participate in the DPA Title III Program and are honored to have subsequently earned MRL 8 designation," said Dr. John Palmour, co-founder of Cree and chief technology officer, Power and RF. "This achievement clearly demonstrates the level of production-readiness that Cree's GaN manufacturing processes are capable of and is a testament to our leadership in the RF GaN industry."

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.
