iDEAL Semiconductor Announces Polar Semiconductor as Manufacturing Partner for SuperQ™ Power Devices

BETHLEHEM, Pa., Sept. 18, 2025 /PRNewswire/ -- iDEAL Semiconductor confirms that its ultra-efficient SuperQ™ silicon power devices are now in production at Polar Semiconductor, a leading foundry specializing in high-voltage, power, and sensor technologies.

SuperQ represents the first major innovation in silicon MOSFET architecture in over 25 years. Leveraging a patented asymmetrical RESURF structure, it significantly reduces conduction and switching losses – with up to 2.7x lower resistance compared to legacy silicon and cutting switching losses by up to 2.1x versus competing devices.

Polar Semiconductor operates a high-volume 200mm manufacturing facility in Minnesota and is the only majority U.S.-owned foundry with deep expertise in high-voltage and power semiconductors. With a 50-year heritage in automotive production, Polar is IATF 16949 certified and committed to zero-defect manufacturing. iDEAL's first products – 150 V and 200 V MOSFETs announced in July – are already in production at Polar, with 300 V and 400 V devices to follow.

Polar is further expanding to double its manufacturing capacity and invest in next-generation technologies to support strategic customers like iDEAL. This enhances Polar's global competitiveness and reflects the growing demand for domestic manufacturing of advanced power and sensor technologies. 

"Polar is among the world's top-tier power semiconductor foundries," said Mark Granahan, CEO and co-founder of iDEAL Semiconductor. "Their advanced manufacturing capabilities, focus on high-voltage processes, partnership mindset, and investment in future capacity make them an ideal choice to support our SuperQ roadmap."

"Polar continues to invest in cutting-edge technologies, and we're excited to collaborate with iDEAL to bring these SuperQ-based devices to market," said Surya Iyer, President and COO of Polar Semiconductor. "Together, we're enabling the next leap in power efficiency and performance while ensuring a secure and scalable manufacturing platform."

SuperQ delivers ultra-low conduction and switching losses while maintaining the ruggedness and manufacturability of silicon – including proven reliability at 175°C junction temperatures. The platform is purpose-built for high-performance applications across industrial automation, automotive electrification, AI datacenters, renewable energy, telecom infrastructure, and consumer power systems.
