Soctera Demonstrates Superior Thermal Performance in GaN HEMTs For Next-Generation Telecommunications and Radar Solutions
Third-party-verified III-Nitride transistors, fabricated on 4-inch wafers produced at IQE, are moving towards commercial production with standard foundry processes.
ITHACA, N.Y., Feb. 9, 2024 /PRNewswire/ -- Soctera, a developer of III-nitride power amplifiers, has demonstrated high-electron-mobility transistors (HEMTs) exhibiting a peak surface temperature rise of just 59 °C while dissipating 10.4 W/mm. Typical gallium nitride (GaN) HEMTs reach the standard operating temperature limit of 225 °C when dissipating approximately 5 W/mm. This dramatic improvement in thermal performance could substantially reduce thermal solution costs, enhance reliability, and increase peak power output in next-generation telecommunications (5G and beyond) and defense radar arrays.
"Reduced heat buildup redefines what is possible for the high-performance communications industry," said Soctera CEO Austin Hickman. "We are delighted with these third-party results and are working now to quickly scale our technology via commercial production methods."
Built on a thermally-optimized III-nitride material stack fully compatible with standard GaN foundry processes, Soctera's HEMTs use 20x less gallium per device, which insulates Soctera's products from supply chain disruptions or price increases arising from potential future restrictions of gallium supply from China. The HEMTs were fabricated at the Cornell Nanoscale Facility and the surface temperature profile was measured with sub-micron resolution via thermoreflectance by Microsanj, LLC.
The 4-inch wafers used in the tests were produced by IQE, a leading global epitaxy manufacturer with whom Soctera has partnered for commercial-scale development. Towards building out end-to-end commercial manufacturing, Soctera has started HEMT fabrication with a DoD-approved GaN foundry.
Soctera's technology maturation efforts were recently bolstered with $750,000 in non-dilutive funding awarded by the Defense Business Accelerator pitch competition.
