    A 6-member team, led by Ozark IC, has been selected for a DARPA HOTS award to develop an 800ºC electronic pressure sensing system that will raise the system performance by a factor of 1000 over existing solutions FAYETTEVILLE, ARKANSAS April 2024 – A 6-member team led by Ozark Integrated Circuits Inc. (Ozark IC) in Fayetteville, AR, has been selected for a $10.9M, three-year DARPA HOTS award. The award will allow the team to develop a high-speed (1 MHz), high-temperature (up to 800ºC) electronic pressure sensing system – which represents orders of magnitude speed increase over the current state-of-the art. DARPA’s HOTS (High Operational Temperature Sensors) Program is a premier program with its major aim to “develop microelectronic sensor technologies capable of high-bandwidth, high-dynamic-range sensing at extreme temperatures” which are critical for emerging high-speed aerospace systems, especially hypersonic flight systems. The Proposer’s Day, held on May 31, 2023, in Washington, DC, attracted about 130 attendees. The HOTS program consists of three significant and simultaneous challenges, each of them extremely difficult on their own: operation at 2 orders-of-magnitude better performance over the state-of-the-art at the very high temperature of 800⁰C without thermal management and a short development time (3 years) to create it. The aggressive timeline put a significant emphasis on the use of existing capabilities rather than long-term research. The team developed a unique and complex approach to meet all three challenges – consistent with DARPA’s mission “to make pivotal investments in breakthrough technologies for national security”. The Ozark IC team consists of: Ozark IC RTX (Raytheon Technologies Research Center and Raytheon Advanced Technology) GE Aerospace Research Center (GEA) IC2 (Interdisciplinary Consulting Corp) NASA Glenn Research Center (NASA GRC) US Naval Research Laboratory (NRL) Ozark IC, as program lead, is managing the system integration as well as electronics design, process integration and extreme environment packaging. Ozark IC will work closely with its partners who will provide the high-speed pressure sensor (IC2), the fabrication of the devices and integrated circuits (RTX, GEA), and specialized materials and characterization (NASA, NRL). Significance of the Project: The HOTS program, like many DARPA programs, aims to advance the state of the art: not incrementally, but by orders of magnitude. The Ozark IC solution, referred to as SPOTS (Single-chip Pressure-Sensor on Thermally-Hardened SiC:GaN) advances the state of the art by combining the ruggedness of NASA Glenn pioneered silicon carbide (SiC) chip technology with the high-performance of gallium nitride (GaN) and other advanced materials. This marks a new era in high-temperature (HT) electronics and integration methods, at the semiconductor level, where very high frequency performance is made possible through utilizing new materials in a manufacturable way – from analog to RF and digital. The effect of this technology will be revolutionary in a wide range of applications and markets, not just the DoD and hypersonic applications: Jet engines can be lighter, smaller and better maintained Engines (ships, tanks, cars, etc.) can be lighter, smaller and better maintained Energy exploration can work deeper and hotter Next-generation nuclear reactors can be safer and better maintained and monitored These are just some of the benefits. A whole new, safer high-temperature world awaits. Dr. A. Matt Francis, CEO and Founder of Ozark IC, said, “In many ways this project is the culmination of over a decade of work at Ozark IC and at our partners to open up new frontiers for electronics. We are naturally thrilled with this award, and we are very grateful to DARPA for the faith they have shown in this amazing team. The support we have received from the team members, and others, has been overwhelming and is greatly appreciated. This is the largest award Ozark IC has received in its 13-year history and we are naturally looking forward to this project and see great things happening as a result.” Arkansas Secretary of Commerce Hugh McDonald, said “This award demonstrates that Arkansas companies compete at the highest level in advancing the state of the art. We build some of the most advanced aerospace, aviation and defense products in the US, and the advanced electronics being developed by Ozark IC and its partners can enable the next generations.” Congressman Steve Womack (AR-3) said, “Ozark IC’s leadership in putting this team together and winning this ground-breaking award is an excellent example of the innovative research happening in the Third District. The technology they are developing will greatly impact jet and hypersonic engine capabilities. This award reflects the importance of these revolutionary systems. It’s great to see these organizations, large and small businesses, and government laboratories coming together to build this research and development partnership in the Natural State.” Dr. David Mills, President of IC2, said, “The HOTS program is the next logical step for our high-performance pressure sensors – an integrated platform for ultra-high-temperature, miniaturized sensors and electronics. This will open up new applications and markets for us, and we’re very excited to be part of the Ozark IC team!” Colin Whelan, President of Advanced Technology at Raytheon, said, “Extreme temperature condition sensing is critical to the operation of military and commercial aircraft. Jet engine and hypersonic vehicle’s operating temperatures well-exceed the capability of today’s sensors in vital locations. In partnership with Ozark IC, RTX is leveraging our enterprise-wide expertise and our III/V semiconductor foundry to develop sensors that deliver accurate state-of-health monitoring and enable closed-loop system control for improved fuel efficiency, operability and lethality.” Stacey Kennerly, Technology Manager, Semiconductors, GE Aerospace Research, said, “We’re thrilled to be partnering with Ozark IC to develop the next generation of high temperature electronics to support defense needs and transform the future of flight. As we look to advance hypersonic propulsion and push the boundaries of space exploration, we will need the kind of ruggedized sensors and electronics that the DARPA HOTS program is driving.” About Ozark Integrated Circuits Inc.

    Ozark IC to use its high-temperature technology for a health monitoring instrument for next-generation nuclear reactors FAYETTEVILLE, ARKANSAS February 2022 – Ozark Integrated Circuits, Inc. (Ozark IC), a Fayetteville-based leader in rugged electronics, recently earned a Small Business Innovation Research (SBIR) Phase I grant from the U.S. Department of Energy. The final one-year contract is still in negotiations and is expected to be nearly $200,000. Ozark IC will use its high-temperature technology to develop a high-temperature health-monitoring instrument that measures the state of molten salts used in molten-salt cooled nuclear reactors (MSRs). Molten salts are used in next-generation nuclear reactors to transfer heat from the reacting fuel or to have nuclear fuel dissolved within the salty fluid itself – thereby providing safe, clean energy. “The opportunity to use our technology to help meet the demand for the safe, clean energy provided by MSRs is both exciting and extremely gratifying” said Dr. Matt Francis, Ozark IC’s Founder and President.  Ozark IC’s specific task involves manufacturing a non-reactive probe using silicon carbide (SiC) and gold materials, which has a proven temperature cycling durability from 500°C to 800°C (930⁰F to 1500⁰F). Ozark IC will also manufacture the analog front-end for the measurement instrument. The project is in conjunction with University of Wisconsin – Madison College of Engineering (UW-M) in Madison, Wisconsin. UW-M will perform measurements to confirm the feasibility of the instrument. “The high temperature technology that Ozark IC brings to MSR development is unique and greatly needed. We are looking forward to testing their MSR health-monitoring instrument,” said Dr. Mark Anderson, Director of the University of Wisconsin’s Thermal Hydraulics Laboratory and the UW-Tantalus facility in Stoughton Wisconsin. “It should provide extremely important capabilities for MSR development and safety.” Francis said he and his team are looking forward to the collaboration. “We are looking forward to this project and working with DOE and the University of Wisconsin,” he said. Molten salt reactors (MSRs) are considered safer than conventional reactors because they operate with fuel already in a molten state, and in event of an emergency, the fuel mixture is designed to drain from the core where it will solidify, preventing the type of nuclear meltdown and associated hydrogen explosions that are at risk in conventional (solid-fuel) reactors[1]. Continuous healthy operation of an MSR heat-exchange loop requires monitoring of the molten salt as it ages and oxidizes. Monitoring of these salts, which can reach temperatures of 500⁰C to 700⁰C, is used to predict when maintenance and/or replacement will be needed. MSRs have received great interest from the DOE and significant investments have been made in several companies to develop MSRs in the US and around the world. There have already been more than three billion federal dollars promised to advance efforts to develop smaller, more flexible nuclear reactor designs. This grant is one of 82 Department of Energy grants totaling $100 million to 68 small businesses in 24 states, including projects relating to wind turbine and wind farms, improved battery electrolytes, solar generation of hydrogen, and upcycling of carbon dioxide, along with a wide range of other efforts. “Supporting small businesses will ensure we are tapping into all of America’s talent to develop clean energy technologies that will help us tackle the climate crisis,” said U.S. Secretary of Energy Jennifer M. Granholm. “DOE’s investments will enable these economic engines to optimize and commercialize their breakthroughs, while developing the next generation of climate leaders and helping to build a sustainable future to benefit all Americans.” Through the SBIR/STTR program across the federal government, small business powers the U.S. economy and generates thousands of jobs, both directly and indirectly, the DOE notes. DOE Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) awards aim at transforming DOE-supported science and technology breakthroughs into viable products and services. The awards also support the development of specialized technologies and instruments that aid in scientific discovery. About Ozark Integrated Circuits Inc.
