The European Commission has approved €319 million in Austrian state aid for Infineon’s plant in Villach, Carinthia, where the German chipmaker plans to invest about €1.1 billion to make gallium nitride (GaN) power semiconductors on 300 mm wafers. Infineon described the plan in announcements reported on October 27, and Euronews published its account on October 28. The company says production is due to start by the end of 2027, and that spending will continue through 2034.

The aid is money from the Austrian state that Brussels has cleared under European Union state-aid rules and the bloc’s Chips Act. Austria’s economy ministry has not yet given its formal funding commitment, according to Infineon’s announcement as reported by The Next Web, Semiconductor Today and Evertiq. The company says the plant would be the first of its kind in the world, a claim that is its own and that the sources reviewed do not test.

What the Commission approved

According to Brussels Times, which reported the Commission’s announcement, the aid is a direct grant to Infineon Technologies Austria AG for a project called “Empowering Fab.” The project extends the company’s existing 200 mm GaN production in Villach by moving to 300 mm wafers. The Commission’s case number is SA.113427, and a non-confidential version of the decision will be published in its state-aid register once confidentiality issues are resolved.

The Commission described the facility as first-of-a-kind in the EU because no comparable 300 mm power GaN capacity exists in the bloc, Brussels Times reports. Euronews quotes the Commission as saying the measure will strengthen the EU’s position and autonomy in the semiconductor value chain. The target uses are artificial intelligence, energy infrastructure, electric mobility and robotics.

Euronews puts the total project at €1.1 billion and says the upgrade is expected to be finished in 2034. Infineon’s own account, as relayed by Evertiq and Semiconductor Today, says the €1.1 billion goes into existing cleanrooms at Villach, which the company says makes the expansion cheaper than building a new plant. Production would ramp according to market demand.

What gallium nitride is for

Power semiconductors are the chips that switch and convert electrical power. Infineon says GaN versions do this more efficiently than silicon ones, which allows smaller, more energy-efficient systems. Euronews lists chargers for phones and laptops, AI data centers, electric vehicles, solar and wind equipment, telecom base stations and robots among the uses.

The company points to the move from 200 mm to 300 mm wafers as the source of the economics. A 300 mm wafer yields about 2.3 times as many chips as a 200 mm wafer, according to Infineon, and the larger wafers are expected to lower costs. Euronews and Evertiq both report that Infineon processed its first 300 mm GaN wafers in 2024 and is now moving the technology toward volume production.

Sources differ on the size of the market. Euronews says analysts forecast the GaN power market will reach about $3.1 billion by 2031, growing roughly 35 percent a year from 2025. Evertiq, summarizing Infineon’s announcement, gives about $3.5 billion by 2031 at the same growth rate and attributes the figure to Yole Group. Both are forecasts rather than measurements, and the two outlets do not explain the gap.

The world’s first claim

Infineon calls Villach the world’s first high-volume GaN power fab on 300 mm wafers, according to Evertiq. Chief executive Jochen Hanebeck went further, saying the company will be the first in the world to bring GaN power electronics into volume production, according to Semiconductor Today. That is a broader statement than the 300 mm claim, as Semiconductor Today notes, and both are statements by the company that the outlets repeat without independent checks.

The Commission’s language is narrower and is tied to the EU. It says there is no comparable 300 mm power GaN capacity in the bloc. This suggests that the regulatory finding concerns Europe’s capacity and not Infineon’s standing against rivals elsewhere, though the sources do not say how the Commission weighed competitors outside the EU.

Conditions on the aid

Brussels Times reports that the Commission attached conditions to the approval. Infineon must expand its collaboration with startups, small and medium-sized companies, universities and research institutions, including access to hardware, software kits and laboratory facilities. It must also develop education and skills-training activities, and share with Austria any project-related profits that exceed current expectations.

The sources reviewed do not describe how the profit threshold is set or how much Austria could receive. Euronews and the other reports likewise do not state how many jobs the plant will create. Infineon employs about 5,800 people in Austria, about 4,800 of them in Villach, according to The Next Web, and Semiconductor Today gives the same figures as of the end of September 2025.

Politicians and the Chips Act

Austrian Chancellor Christian Stocker called the project “one of the largest single investments in the history of Austria’s high-tech industry,” according to The Next Web and Semiconductor Today. Euronews adds that he said it helps keep the future of chipmaking from being decided only in Asia or the United States. Economy Minister Wolfgang Hattmannsdorfer said, as quoted by Semiconductor Today, that Europe accounts for only about 10 percent of global chip production, and estimated that each job in the chip industry supports six more across the wider economy. That multiplier is the minister’s estimate and was not independently sourced.

Euronews says the EU wants its share of global chip production to rise from 10 percent in 2023 to 20 percent by 2030. The Commission’s own Chips Act page, which does not repeat the 20 percent target, says the regulation took effect on September 21, 2023, and that the Commission has approved 19 state-aid decisions for first-of-a-kind semiconductor facilities, representing more than €33 billion in combined public and private investment. The page lists Infineon’s earlier project in Dresden among them, with a figure of €3.54 billion, alongside projects by ST Microelectronics, GlobalFoundries and ESMC. It also says the Commission proposed a follow-up, Chips Act 2.0, in June 2026.

What to watch

The first open item is Austria’s formal funding commitment. Infineon and the trade outlets all say the economy ministry’s confirmation is still expected, and Semiconductor Today reports it depends on clear funding criteria for the location. Until it arrives, the €319 million is an approved ceiling and not a disbursed sum.

The Next Web also reports that Infineon shares rose almost 1 percent in early Frankfurt trading on Tuesday, October 27, after falling about 40 percent since mid-June. That figure comes from a single outlet and was not checked against an exchange. Whether the move reflected the announcement is not established.

The remaining unknowns are the ones the reports leave open: the number of jobs, how the profit-sharing terms will be calculated, and whether output starts on the end-2027 schedule, since Infineon says the ramp-up will follow market demand. The reports also describe 2034 slightly differently. Euronews calls it the expected finish of the upgrade, while Infineon’s announcement presents it as the end of the investment period, with production starting by the end of 2027.
