X-FAB partners Exagan to produce GaN-on-Silicon devices on 200-mm wafers
The two companies are planning to establish a European production center where the two partner companies will manufacture GaN devices for the solar, industrial, automotive, IT electronics and other markets. The two companies already have begun to demonstrate their capabilities by processing the first GaN-on-silicon devices built on 200 mm substrates at X-FAB’s wafer fab in Dresden, Germany, and now are transforming that prototype into a process robust enough for the mass production environment.
Working with CEA-Leti in Grenoble, where some process steps are performed, X-FAB and Exagan are manufacturing the first of Exagan’s G-FET 650 Volt, fast-switching power devices on 200 mm substrates using a standard silicon manufacturing line. To date, the global semiconductor industry’s work with GaN has been limited to 100 mm and 150 mm wafers due to the challenges of creating the required GaN layers on silicon substrates. Without the ability to use larger wafers in mass production, GaN-based semiconductors have not been available at a competitive price-performance point compared to other power-switching alternatives. Exagan’s breakthrough G-Stack technology enables GaN-on-silicon devices to be manufactured economically on 200 mm substrates by depositing a unique stack of GaN and strain management layers that alleviates the stress between bonded GaN and silicon layers. The resulting G-FET devices meet customer requirements for high breakdown voltage, low vertical leakage and high-temperature operation. The advanced semiconductors also allow greater power integration, which improves the efficiency and reduces the cost of electrical converters.
“Our strategic partnership with X-FAB is the latest step in establishing a robust supply chain capable of providing customers with qualified GaN devices in large volumes for demanding applications,” said Frédéric Dupont, president and CEO of Exagan. “The industry has long acknowledged the performance and efficiency advantages of GaN devices. We are now driving GaN market penetration to the next level by providing these devices at an attractive price-performance point.”
“X-FAB’s leadership position as a pure-play foundry for More-than-Moore technologies is reinforced by this new alliance and our commitment to innovative nanufacturing,” said Dr. Jens Kosch, X-FAB’s chief technology officer. “We are proud to support the successful industrialization of Exagan’s novel technology, which we believe will have a major impact on the future of automotive and industrial markets.”
