Infineon buys GaN Systems

The company provides GaN-based solutions for power conversion. It has more than 200 employees.

“GaN technology is paving the way for more energy-efficient and CO ₂-saving solutions that support decarbonization. Adoption in applications like mobile charging, data centre power supplies, residential solar inverters, and onboard chargers for electric vehicles is at the tipping point, leading to a dynamic market growth,” said Jochen Hanebeck (pictured), CEO of Infineon. “The planned acquisition of GaN Systems will significantly accelerate our GaN roadmap, based on unmatched R&D resources, application understanding and customer project pipeline. Following our strategy, the combination will further strengthen Infineon’s leadership in Power Systems through mastery of all relevant power technologies, be it on silicon, silicon carbide or gallium nitride.”

Jim Witham, CEO of GaN Systems, commented: “The GaN Systems team is excited about teaming up with Infineon to create highly differentiating customer offerings, based on bringing together complementary strengths. With our joint expertise in providing superior solutions, we will optimally leverage the potential of GaN. Combining GaN Systems’ foundry corridors with Infineon’s in-house manufacturing capacity enables maximum growth capability to serve the accelerating adoption of GaN in a wide range of our target markets. I am very proud of what GaN Systems has accomplished so far and cannot wait to help write the next chapter together with Infineon. As an integrated device manufacturer with a broad technology capability, Infineon enables us to unleash our full potential.”

As a wide bandgap material, GaN offers customer value by higher power density, higher efficiency, and size reductions, especially at higher switching frequencies.

These properties enable energy savings and smaller form factors, making GaN suited for a wide range of applications.

By 2027, market analysts expect the GaN revenue for power applications to grow by 56% CAGR to approx. US$2 billion (source: Yole, Compound Semiconductor Market Monitor-Module I Q4 2022).

As such, GaN is becoming a key material for power semiconductors, alongside silicon and silicon-carbide, and coupled with new topologies, such as Hybrid Flyback and multi-level implementations.

In February 2022, Infineon announced doubling down on wide bandgap by investing more than €2 billion in a new front-end fab in Kulim, Malaysia.

The first wafers will leave the fab in the second half of 2024, adding to Infineon’s existing wide bandgap manufacturing capacities in Villach, Austria.
