The University of Arkansas celebrated an important milestone with the groundbreaking on a building that Chancellor Charles Robinson suggested might someday rival the U of A’s most iconic structure, Old Main, in significance to the university and the state of Arkansas.
Robinson and other university leaders, including University of Arkansas System President Don Bobbitt and members of the U of A System Board of Trustees, as well as researchers and industry leaders, gathered at the Arkansas Research and Technology Park in South Fayetteville to celebrate construction of the national Multi-User Silicon Carbide Research and Fabrication Facility, or MUSiC.
The new semiconductor research and fabrication facility will produce microelectronic chips made with silicon carbide, a powerful semiconductor that outperforms basic silicon in several critical ways. The facility will enable the federal government – via national laboratories – businesses of all sizes, and other universities to prototype with silicon carbide, a capability that does not presently exist elsewhere in the U.S.
Work at the facility will bridge the gap between traditional university research and the needs of private industry and will accelerate technological advancement by providing a single location where chips can go from developmental research to prototyping, testing and fabrication.
“This fills a gap for our nation, allowing companies, national laboratories and universities around the nation to develop the low-volume prototypes that go from their labs to fab, ultimately scaling up to the high-volume manufacturing…” said Alan Mantooth, Distinguished Professor of electrical engineering and principal investigator for the MUSiC facility. “We fill that gap. And there’s no other place like it in the world. This is the only place that will be able to do that with silicon carbide.”
The 18,660 square-foot facility, located next to the National Center for Reliable Electrical Power Transmission at the research and technology park, will address obstacles to U.S. competitiveness in the development of silicon-carbide electronics used in a wide range of electronic devices, circuits and other consumer applications. The building will feature approximately 8,000 square feet of clean rooms for fabrication and testing.
Education and training within the facility will also accelerate workforce development, helping supply the next generation of engineers and technicians in semiconductor manufacturing, which Mantooth and other leaders have said is critical for bringing semiconductor manufacturing back to the U.S., after it was offshored in the late 1990s and early 2000s.
“This is truly a special day in the life of the University of Arkansas,” said Robinson. “This building, it really doesn’t need to be hyped. It is a very important building, and you just know it, important for our university, important for our state, important for our nation.”
Robinson invoked another groundbreaking, that of Old Main, the university’s oldest and best known structure, which the university celebrated Aug. 17, 1873, almost exactly 150 years ago.
“I took that 150th anniversary of the groundbreaking as a good sign that we are moving in a timely way,” Robinson said, “doing important work in establishing this building.”
Friday’s groundbreaking occurred a day after the university and the Arkansas Department of Commerce hosted the CHIPS AMERICA Summit, an event in which research, industry and governmental leaders discussed semiconductor-related opportunities resulting from the CHIPS (Creating Helpful Incentives to Produce Semiconductors) and Science Act passed by Congress in 2022. The event featured Adrienne Elrod, director of external and government affairs for the U.S. Department of Commerce’s CHIPS Program Office, U.S. Rep. Steve Womack and Arkansas Secretary of Commerce Hugh McDonald.
During the summit, Elrod stated that prior to the coronavirus pandemic, 90% of the world’s leading-edge chips were manufactured at one facility in Taiwan. The federal government prioritized the onshoring of this critical technology as a result of manufacturing and production shortages of essential computer chips during the pandemic.
“If America is going to compete and lead the world over the next century, we must invest in our technology and manufacturing,” Elrod said. “We want to make sure, at the very least, that we have two new large-scale clusters of leading- edge fabs created (in the United States).”
As Mantooth mentioned, the University of Arkansas can contribute to this effort on a fundamental level and is uniquely positioned to take advantage of opportunities offered by the CHIPS and Science Act, which is providing approximately $280 billion in funding to stimulate domestic research and manufacturing of semiconductors.
“The university is leaning forward and has now secured funding for projects important to microelectronics research and development,” Womack said during Thursday’s summit. “The university has positioned itself, as I say often, to be the preeminent university research location for microelectronics. … I am grateful for the bright minds at the University of Arkansas with a proven track record of success who will make this happen.”

Toshiba Electronic Devices & Storage Corporation has launched two automotive 40V N-channel power MOSFETs, “XPJR6604PB” and “XPJ1R004PB,” that use Toshiba’s new S-TOGL™ (Small Transistor Outline Gull-wing Leads) package with U-MOS IX-H process chips. Volume shipments start today.
Safety-critical applications like autonomous driving systems ensure reliability through redundant design, with the result that they integrate more devices and require more mounting space than standard systems. Accordingly, advancing size reductions in automotive equipment requires power MOSFETs that can be mounted at high current densities.
XPJR6604PB and XPJ1R004PB use Toshiba’s new S-TOGL™ package (7.0mm×8.44mm) which features a post-less structure unifying the source connective part and outer leads. A multi-pin structure for the source leads decreases package resistance.
The combination of the S-TOGL™ package and Toshiba’s U-MOS IX-H process achieve a significant On-resistance reduction of 11% against Toshiba’s TO-220SM (W) package product, which has the same thermal resistance characteristics. The new package also cuts the required mounting area by approximately 55% against the TO-220SM(W) package.
On top of this, the 200A drain current rating of the new package is higher than Toshiba’s similarly sized DPAK + package (6.5mm×9.5mm), enabling high current flow. Overall, the S-TOGL™ package realizes high-density and compact layouts, reduces the size of automotive equipment, and contributes to high heat dissipation.
Since automotive equipment is used in extreme temperature environments, the reliability of surface mounting solder joints is a critical consideration. The S-TOGL™ package uses gull-wing leads that reduce mounting stress, improving the reliability of the solder joint.
Assuming that multiple devices will be connected in parallel for applications requiring higher-current operation, Toshiba supports grouping shipment for the new products, in which the gate threshold voltage is used for grouping. This allows designs using product groups with small characteristic variation.
Toshiba will continue to expand its product line-up of power semiconductor products and contribute to the realization of carbon neutrality with more user-friendly, high-performance power devices.
Features:
- New S-TOGL™ package: 7.0mm×8.44mm (typ.)
- Large drain current rating:
XPJR6604PB: ID=200A
XPJ1R004PB: ID=160A - AEC-Q101 qualified
- IATF 16949/PPAP available[4]
- Low On-resistance:
XPJR6604PB: RDS(ON)=0.53mΩ (typ.) (VGS=10V)
XPJ1R004PB: RDS(ON)=0.8mΩ (typ.) (VGS=10V)

The U.S. Department of Energy (DOE)’s Advanced Materials and Manufacturing Technologies Office (AMMTO) announced renewed funding for PowerAmerica, DOE’s first Clean Energy Manufacturing Innovation Institute. PowerAmerica will receive an initial $8 million, with potential funding across four more fiscal years to follow, to continue advancing domestic manufacturing of next-generation WBG semiconductors for power electronics to aid economy-wide decarbonization and electrification.
WBG semiconductors use cutting-edge materials that enable power electronics that are used in a range of applications—including industrial equipment, data centers, consumer devices, electric vehicles, and more. Silicon carbide (SiC) and gallium nitride (GaN) WBG semiconductor technology makes the power electronic modules significantly more powerful and energy efficient than those made from conventional semiconductor materials, namely silicon. These high-performance power electronics can increase electric vehicle driving range; help integrate renewable energy into the electric grid; and lead to significant energy savings.
“The work PowerAmerica—and its 82 member organizations spanning industry, academia, and national labs—is doing to galvanize commercialization of high-performance power electronics is invaluable to our clean energy future,” said AMMTO Director Chris Saldaña. “PowerAmerica has catalyzed an innovation ecosystem that touches nearly every sector up and down each supply chain.”
Raleigh-based PowerAmerica commercialized more than 10 WBG technologies over five years. To date, 40 percent of PowerAmerica’s 60 projects have reached or are set to reach commercial status.
Not only is PowerAmerica innovating semiconductors that surpass operational limitations of traditional silicon-based designs, but it also focuses on training the future workforce of America’s manufacturing sector through its strong education and workforce development (EWD) program. Since launching in 2014, PowerAmerica has trained more than; 400 masters and PhD students, 300 short course attendees, 1,800 tutorial participants, and 9,000 K-12 students in STEM programs, including 2,000 participants of hands-on trainings. These numbers are particularly important in addressing the acute workforce shortage the power electronics industry faces, and scaling up PowerAmerica’s existing EWD program is a proposed focus of the new federal funding.
This federal funding builds upon initial federal funding of $70 million, in addition to $81 million in cost share from its member partners, for a total of $151 million.
PowerAmerica is one of seven Clean Energy Manufacturing Innovation Institutes supported by two of DOE’s Energy Efficiency and Renewable Energy program offices: the Advanced Materials and Manufacturing Technologies Office (AMMTO) and Industrial Efficiency and Decarbonization Office (IEDO). In addition, PowerAmerica is one of the 16 member institutes of Manufacturing USA™, a national network of manufacturing innovation institutes created to secure U.S. global leadership in advanced manufacturing through large-scale public-private collaboration on technology, supply chain, and education and workforce development.
