Infineon Technologies announced that the company has succeeded in developing the world’s first 300 mm power gallium nitride (GaN) wafer technology. Infineon is the first company in the world to master this groundbreaking technology in an existing and scalable high-volume manufacturing environment.
Infineon has succeeded in manufacturing 300 mm GaN wafers on an integrated pilot line in existing 300 mm silicon production in its power fab in Villach (Austria). Infineon will further scale GaN capacity aligned with market needs. 300 mm GaN manufacturing will put Infineon in a position to shape the growing GaN market which is estimated to reach several billion US-Dollars by the end of the decade.
A significant advantage of 300 mm GaN technology is that it can utilize existing 300 mm silicon manufacturing equipment, since gallium nitride and silicon are very similar in manufacturing processes. Infineon’s existing high-volume silicon 300 mm production lines are ideal to pilot reliable GaN technology, allowing accelerated implementation and efficient use of capital. Fully scaled 300 mm GaN production will contribute to GaN cost parity with silicon on R DS(on) level, which means cost parity for comparable Si and GaN products.
GaN-based power semiconductors find fast adoption in industrial, automotive, and consumer, computing & communication applications, including power supplies for AI systems, solar inverters, chargers and adapters, and motor-control systems. State-of-the art GaN manufacturing processes lead to improved device performance resulting in benefits in end customers’ applications as it enables efficiency performance, smaller size, lighter weight, and lower overall cost. Furthermore, 300 mm manufacturing ensures superior customer supply stability through scalability. The breakthrough will help substantially drive the market for GaN-based power semiconductors.
