Infineon achieves breakthrough in 300mm gallium nitride production roadmap

With the continued growth in demand for gallium nitride (GaN) semiconductors, Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) is capitalising on this trend to strengthen its position as the leading vertically integrated manufacturer (IDM) in the GaN market. Recently, the company announced that its scalable GaN production on 300mm wafers is now on track. With the first samples set to be delivered to customers in the fourth quarter of 2025, Infineon is poised to expand its customer base and further solidify its position as a leading GaN giant.

Infineon 300mm GaN technology

As a leader in the power systems field, Infineon has mastered the relevant technologies for all three materials: silicon (Si), silicon carbide (SiC) and gallium nitride (GaN). With higher power density, faster switching speeds, and lower power losses, GaN semiconductors enable more compact designs, thereby reducing energy consumption and heat generation in electronic devices such as smartphone chargers, industrial and humanoid robots, and solar inverters.

Johannes Schoiswohl, Head of Infineon's GaN Business Line, stated: Infineon's significantly expanded 300mm GaN production capacity will enable us to deliver higher-value products to our customers faster while driving cost parity between Si and GaN products. Nearly a year after Infineon announced its breakthrough in 300mm GaN wafer technology, we are pleased to see our transition progressing smoothly, and the industry has recognised the important role Infineon's GaN technology plays under our IDM strategic advantage."

Infineon's production strategy is primarily based on the IDM model, which involves owning the entire semiconductor production process from design to manufacturing and sales of the final product. The company's internal production strategy is a key differentiator in the market, offering multiple advantages such as higher-quality products, faster time-to-market, and excellent design and development flexibility. Infineon is committed to supporting GaN customers and can expand capacity to meet their demand for reliable GaN power solutions.

With its technological leadership, Infineon has become the first semiconductor manufacturer to successfully develop 300mm GaN power wafer technology within its existing high-volume production infrastructure. Compared to existing 200mm wafers, chip production on 300mm wafers is technically more advanced and significantly more efficient, as the larger wafer diameter enables a 2.3-fold increase in chip production efficiency. These enhanced capabilities, combined with Infineon's strong team of GaN experts and the industry's broadest intellectual property portfolio, are ideally suited to meet the rapid adoption of GaN-based power semiconductors across industrial, automotive, consumer, computing, and communications applications, including AI system power supplies, solar inverters, chargers and adapters, and motor control systems.

Market analysts predict that revenue from GaN in power applications will grow at an annual rate of 36% to reach approximately $2.5 billion by 2030[1]. Infineon possesses dedicated production capabilities and a robust product portfolio, having launched over 40 new GaN products last year, making it the preferred partner for customers seeking high-quality GaN solutions.
