Development of 45-Nanometer Radiation-Hardened Space Microelectronics

BAE Systems has secured 16 million dollars in federal funding to qualify its radiation-hardened RH45 microelectronics technology for aerospace applications. To achieve this, the company is collaborating with GlobalFoundries to manufacture custom application-specific integrated circuits for space-grade digital infrastructure.

Industrial Challenge and Partnership Roles
Operating electronic systems in space requires components capable of withstanding severe natural and strategic radiation environments without performance degradation or critical failure. To address this operational challenge, the Department of War allocated the 16 million dollars in Defense Production Act Title III funding to support the qualification of 45-nanometer silicon-on-insulator technology. BAE Systems manages the design architecture, platform qualification, and component integration, while GlobalFoundries handles the physical semiconductor manufacturing. This cooperation leverages GlobalFoundries' established fabrication scale and BAE Systems' specialized aerospace engineering expertise to maintain a secure, domestic supply of radiation-hardened hardware.

Technical Solution and System Architecture
The technical foundation of this initiative is the RH45 application-specific integrated circuit (ASIC) platform. This system functions as a library of qualified digital building blocks that are compatible with standard industry design tools, enabling spacecraft engineers to generate custom integrated circuit layouts. GlobalFoundries manufactures these designs utilizing its 45-nanometer silicon-on-insulator fabrication process at its facility in Malta, New York. The resulting microprocessors offer higher transistor density and lower power consumption compared to preceding generations, while the insulating layer in the silicon substrate mitigates latch-up events and soft errors caused by ionizing radiation.

Implementation and Infrastructure Integration
Engineering, packaging, and final testing operations are executed by the BAE Systems Space Systems group in Manassas, Virginia. This facility operates as a Department of War Category 1A Microelectronics Trusted Source, ensuring secure handling of the components. Following fabrication, BAE Systems integrates the 45-nanometer microprocessors into standardized hardware configurations, such as single-board computers. These computer modules incorporate processor cores, advanced security protocols, and hardware-accelerated input/output channels to streamline hardware integration into existing orbital payloads.

Applications and Operational Impact
These radiation-hardened components are engineered for deployment in satellite communications, planetary exploration probes, weather monitoring systems, and national security surveillance platforms. By utilizing a modular ASIC framework, manufacturers can configure processing functions specific to their mission parameters without compromising on environmental resilience.

"Design flexibility is important when it comes to supporting space missions," said Joe Dziezynski, Space Systems product line director at BAE Systems. "Our RH45 ASIC library is a unique and trusted capability that allows our customers to target specific functions while meeting radiation-hardened requirements."

The reestablishment of this manufacturing process ensures that complex computational tasks, which require high processing power and absolute reliability, can be executed effectively in challenging orbital environments.
