The European Commission has authorised €319 million of Austrian state aid to support Infineon’s planned expansion in Villach, Austria, a decision the company says will underpin a roughly €1.1 billion investment to build Europe’s first high‑volume gallium‑nitride (GaN) power‑semiconductor line on 300‑millimetre wafers. The Infineon announcement and subsequent reporting put the date of the announcement at 27 October 2026, and Infineon says production is scheduled to begin by the end of 2027.

What was approved and why it matters

Infineon’s “Empowering Fab” project will upgrade existing cleanroom capacity at Villach and move GaN power device manufacturing from 200 mm to 300 mm wafer processing, a step the company says yields roughly 2.3 times more chips per wafer and makes GaN more cost‑competitive at scale. The company and multiple press reports describe the facility as the world’s first high‑volume 300 mm GaN power‑semiconductor line and say the expansion targets markets including AI data‑centre supplies, energy infrastructure and electric mobility. Infineon’s press release and coverage of the Commission decision set the investment horizon through 2034 with an initial production start target of end‑2027.

The Commission’s state‑aid clearance noted that the grant fills a demonstrable funding gap and was authorised under the EU Chips Act / state‑aid rules; the non‑confidential version of the decision will be published in the EU state‑aid register once confidentiality issues are resolved. News services reporting the clearance emphasised that EU authorisation does not mean funds have yet been disbursed — Austria must formalise the national funding commitment and fulfil the conditions set out by Brussels.

What this means for the market

For Central and Eastern Europe’s auto sector the Villach decision is strategically important. GaN power semiconductors are used in on‑board chargers, DC fast chargers, inverters and other power‑conversion hardware that feature in battery electric vehicles and charging infrastructure — areas where demand is rising with EV adoption. A viable, large‑volume European GaN supply could reduce lead times, ease component shortages and lower costs for power electronics over the medium term, improving the resilience of automotive supply chains that now depend heavily on Asian suppliers. Infineon explicitly links the investment to e‑mobility among other end markets.
