BAE Systems advancing USAF developed GaN semiconductor tech

Posted 2 October 2019 · Add Comment

BAE Systems is working to transition short-gate gallium nitride (GaN) semiconductor technology developed by the US Air Force (USAF) to its open foundry service.

BAE Systems has successfully completed a Phase 1 effort to transition short-gate gallium nitride (GaN) semiconductor technology developed by the US Air Force to its Advanced Microwave Products (AMP) Center.

BAE Systems were also selected by the Air Force Research Laboratory (AFRL) for Phase 2 of the programme.

The GaN semiconductor technology comes in the form of a wafer that provides high efficiency and broad-frequency bandwidth capabilities in a compact form that can be integrated into a variety of systems to enable next-generation radar, electronic warfare, and communications.

As part of Phase 2, the BAE Systems FAST Labs research and development team and the AMP Center will collaborate to further develop and advance the readiness of the technology. Specifically, the project will scale the 140-nanometer GaN monolithic microwave integrated circuit (MMIC) technology to six-inch wafers and increase its manufacturing level of maturity as part of the validation process, which will include optimising performance, ensuring process stability and maximising wafer-to-wafer uniformity and wafer yields. ENGIN-IC, a custom MMIC design company, will support the design activities, including process design kit validation.

This technology will transition to a foundry service product, available through our open foundry service, at the end of Phase 2, where the technology can be leveraged more broadly across different government initiatives.

"Our foundry is a trusted partner to the defence community because it is dedicated to the design, creation, and implementation of vital technologies such as short-gate GaN," said Chris Rappa, product line director for Radio Frequency, Electronic Warfare and Advanced Electronics at BAE Systems FAST Labs. "GaN technology fills a unique need for the Department of Defense for low-cost, high-performance amplifier technology and Phase 2 of this effort brings us one step closer to successfully manufacturing and bringing AFRL's technology to market."

BAE Systems is researching and advancing microelectronic technologies, including GaN, in our 70,000-square-foot Microelectronics Center (MEC) located in Nashua, New Hampshire. The MEC has been an accredited DoD Category 1A Trusted Supplier since 2008 and fabricates integrated circuits in production quantities for critical DoD programmes.
