Infineon Launches 300mm GaN Production: What This Means

TVS News AI redaktionell betreut präsentiert Infineon startet 300-mm-GaN-Fertigung: Was das bedeutet.

With 300-millimeter wafers, Infineon is taking gallium nitride into an unprecedented scale: according to the company, it is building the world's first factory in Villach to produce GaN power semiconductors in volume on 300-millimeter wafers. For you, this is particularly interesting because larger wafers can accommodate more components per disc – and thus advance the industrialization of power electronics.

The catch: this is not an ordinary factory expansion. GaN is a young technology, production is demanding, and Infineon is relying on a manufacturing technique that has so far mainly been tested on a small scale. EU subsidies help cushion this risk.

Location: Villach, Austria. Timing: Infineon has announced the expansion; the heise online report carries November 21, 2025 in its headline. The focus is therefore clear: the next hurdle for GaN is no longer technical performance alone, but reliable mass production.

What the 300mm production in Villach is expected to change

Larger wafers, higher volumes

300 millimeters is considerably more than the small discs that have typically been used for GaN so far. More chips can be produced simultaneously on a larger wafer. This generally lowers the cost per component, provided production runs stably and there is sufficient demand.

Power semiconductors instead of conventional semiconductors

Gallium nitride, or GaN for short, is used in power electronics. The source emphasizes that Infineon wants to produce the semiconductors in volume. Mass production is therefore moving to the center of attention – from demonstrating individual components to an industrial product.

Why the expansion is strategically important for the EU

The factory will be supported by EU subsidies. This is a clear signal: the European Union wants to strengthen semiconductor manufacturing and the technology it requires in Europe. Infineon is thus not only receiving funding for a new production line, but also building a kind of practical showcase for high-volume GaN production.

At the same time, the step shows how big the challenge remains. GaN not only has to work, but also be manufactured reliably in large quantities. That is a different dimension from developing individual prototypes.

What follows from the announcement – and what remains open

The central message is clear: Infineon is launching the world's first 300mm high-volume production for GaN power semiconductors in Villach. Competition over efficient GaN production is therefore entering a new phase.

The source leaves questions open regarding the exact production start, planned volumes, and concrete cost advantages. For a reliable assessment, it would also be important to know how reliably production runs and which applications the larger batches reach. The announced factory alone does not yet reveal how large or economically successful production will actually be.

Your Added Value

If you are following GaN, Europe's semiconductor strategy, or the industrialization of new power electronics, Villach is a central stage. It is here that it will become clear whether the previous R&D stage can make the leap into series production.
