Infineon Advances on 300-millimeter GaN Manufacturing Roadmap as Leading Integrated Device Manufacturer (IDM)

Estimated reading time: 2 minutes

As the demand for gallium nitride (GaN) semiconductors continues to grow, Infineon Technologies AG is poised to capitalize on this trend and solidify its position as a leading Integrated Device Manufacturer (IDM) in the GaN market. The company announced that its scalable GaN manufacturing on 300-millimeter wafers is on track. With first samples available for customers as of the fourth quarter of 2025, Infineon is well-positioned to expand its customer base and reinforce its position as a leading GaN powerhouse.

As a leader in power systems, Infineon is mastering all three relevant materials: silicon (Si), silicon carbide (SiC) and gallium nitride. With higher power density, faster switching speeds, and lower power losses, GaN semiconductors enable smaller designs, reducing energy consumption and heat generation in electronic devices like smartphone chargers, industrial and humanoid robots or solar inverters.

“Our fully scaled-up 300-millimeter GaN manufacturing will allow us to deliver highest value to our customers even faster while moving towards cost parity for comparable silicon and GaN products,” said Johannes Schoiswohl, Head of GaN Business Line at Infineon. “Almost a year after the announcement of Infineon’s breakthrough in 300-millimeter GaN wafer technology, we are pleased that our transition process is well on track and that the industry has recognized the importance of Infineon’s GaN technology enabled by the strength of our IDM strategy.”

Infineon’s manufacturing strategy primarily relies on an IDM model – owning the entire semiconductor production process, from design to manufacturing and selling the final product. The company’s in-house manufacturing strategy is a key differentiator in the market providing several advantages such as high-quality, faster time-to-market as well as superior design and development flexibility. Infineon is committed to supporting its GaN customers and can scale capacity to meet their needs for reliable GaN power solutions.

Building on its technology leadership, Infineon has become the first semiconductor manufacturer to successfully develop 300-millimeter GaN power wafer technology within its existing high-volume manufacturing infrastructure. Chip production on 300-millimeter wafers is technically more advanced and significantly more efficient compared to established 200-millimeter wafers, as the larger wafer diameter allows 2.3 times more chips to be produced per wafer. These increased capabilities combined with Infineon’s large team of GaN experts and the industry’s broadest IP portfolio are needed as GaN power semiconductors are being rapidly adopted in industrial, automotive, consumer, and computing & communication applications, such as power supplies for AI systems, solar inverters, chargers and adapters or motor control systems.
