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