Infineon to Deliver First 12-Inch GaN Samples in Q4

Recently, Infineon announced that its scalable GaN (gallium nitride) production on 300mm (12-inch) wafers is now on track, with the first customer samples expected to ship in Q4 2025. This advancement positions Infineon to broaden its customer base and reinforce its role as a global leader in GaN power technology.

As a key player in the power systems domain, Infineon is uniquely equipped with expertise across all three key semiconductor materials: silicon (Si), silicon carbide (SiC), and gallium nitride (GaN). GaN technology enables more compact and energy-efficient designs thanks to its higher power density, faster switching speeds, and reduced power losses—making it ideal for applications like smartphone chargers, industrial and humanoid robotics, and solar inverters.

Johannes Schoiswohl, Head of Infineon's GaN business line, stated: “The full-scale expansion of our 300mm GaN production will accelerate the delivery of high-value solutions to our customers while advancing cost parity between Si and GaN-based products. Nearly a year after our breakthrough in 300mm GaN wafer technology, we're pleased to report solid progress, with the industry recognizing GaN’s strategic importance under Infineon's IDM model.”

Infineon's integrated device manufacturer (IDM) strategy—covering the entire semiconductor value chain from design to final product—continues to be a strategic differentiator. This model enables higher product quality, faster time-to-market, and greater design flexibility. The company remains committed to supporting GaN technology adoption at scale and addressing the growing demand for reliable, high-performance GaN power solutions.

Infineon is now the first semiconductor manufacturer to successfully develop 300mm GaN power wafer technology within an existing high-volume production infrastructure. Compared to 200mm wafers, 300mm wafers enable 2.3x greater production efficiency, offering a significant technical edge. Combined with a robust GaN R&D team and one of the industry's most comprehensive IP portfolios, Infineon is well-positioned to meet the accelerating demand for GaN-based power semiconductors across industrial, automotive, consumer, computing, and communications sectors—including AI system power, solar inverters, chargers and adapters, and motor control systems.

Industry analysts predict GaN-based power applications will grow at a compound annual rate of 36%, reaching a market size of approximately $2.5 billion by 2030. With over 40 new GaN products launched last year and dedicated manufacturing capabilities, Infineon is poised as a top choice for companies seeking high-performance GaN solutions.
