TL;DR — three sentences

  • Polar Semiconductor and imec IC-Link will produce enhancement-mode GaN-on-Si devices on 8-inch wafers at Polar's Bloomington, MN foundry. (S1)
  • The program is enabled by a license transfer of imec's GaN-on-Si process, device, and epitaxy to Polar. (S1)
  • Initial voltage range is 40 to 650V, with planned expansion across the GaN power spectrum including 800V-to-12V data-center conversion. (S1)

What happened

On , Polar Semiconductor and IC-Link by imec said they are collaborating to provide 8-inch production of enhancement-mode (e-mode) GaN devices on silicon, with Polar manufacturing the parts at its power and sensor foundry in Bloomington, Minnesota. S1

The program is enabled by a license transfer agreement covering imec's GaN-on-Si process, device, and epitaxy to Polar. S1 The initial focus is 40 to 650V, with future expansion planned toward both lower and higher voltages across the GaN power spectrum, including 800V-to-12V conversion for data centers. S1

Through IC-Link, imec's design and manufacturing service, customers can obtain early access to the technology for prototyping and then transition to volume manufacturing at Polar. S1 Reza Kazerounian, Executive Chairman of Polar, framed the deal as part of a push to build a U.S.-based GaN Center of Excellence serving defense, AI, and automotive supply chains. S1 Thomas Piliszczuk, Chief R&D Programs & Portfolio Officer at imec, cited more than 15 years of imec GaN R&D as the technology base being transferred. S1

Target markets listed by the partners are AI data centers, automotive, aerospace & defense, and the industrial grid. S1

XAIPART take

Technical impact

XAIPART analysis An 8-inch e-mode GaN-on-Si line landing inside a U.S. high-voltage power fab is a relevant addition for designers targeting normally-off behavior with simple gate drive, since e-mode parts simplify circuit topology versus cascode or depletion-mode devices.

XAIPART analysis The 40-650V envelope covers the bulk of today's GaN opportunities (USB-PD adapters, server POL converters, OBC, industrial motor drive). Extending above 650V will matter for traction and grid-adjacent roles, but the partners name 800V-to-12V data-center conversion as the headline use case, so expect first PDKs and demo parts to skew toward 100/200V server-side converters.

Market impact

XAIPART analysis For procurement, a domestic 8-inch GaN line competes with existing Asia-based 6/8-inch GaN-on-Si capacity for allocation cycles; the source does not give wafer-start capacity or pricing, so qualification timing rather than spot price is the first lever to watch. Aerospace & defense and AI data-center dual-use positioning aligns with U.S. policy interest in onshore power-semiconductor supply.

XAIPART analysis Imec's IC-Link provides a prototyping front-end, which compresses the typical design-to-Polar-production handoff and could shorten multi-quarter evaluation cycles for design-in teams selecting a second source.

Action

XAIPART analysis Engineers evaluating 100-650V high-efficiency converters should request Polar's 8-inch GaN PDK and access path through IC-Link, and confirm JEDEC- or AEC-relevant qualification evidence before committing.

XAIPART analysis Buyers should ask Polar for an allocation roadmap and pin a second-source policy in writing, since the source discloses neither wafer-start capacity nor volume-pricing at announcement.

XAIPART Forecast

XAIPART analysis XAIPART expects Polar's 8-inch GaN-on-Si line to surface a customer-qualified 100/200V e-mode GaN device listed on Polar's product page before ; if Polar has not published a customer-qualified e-mode GaN part number by that date, this forecast is wrong.

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. Uncertainty: wafer-start capacity, lead time, qualification status (e.g., AEC-Q100/Q101), pricing and mass-production timing are not disclosed by the source and remain single-source until further data appears.

Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
