Radiation Assured Semiconductors for Strategic Autonomy

Radiation-Aware Semiconductor Design

Semiconductors used in space and defence systems must operate reliably under radiation exposure. Effects such as total ionizing dose and single event effects can degrade or permanently damage electronic systems. Current radiation-tolerant semiconductor development is highly iterative and often integrates mitigation strategies late in the design cycle. RASSS introduces a structured methodology in which radiation constraints are embedded at the architectural level from the earliest design stages.

Predictive Workflow and Radiation Modelling Integration

RASSS develops a predictive semiconductor design workflow that integrates structured requirement formalisation, architectural exploration and radiation modelling. Radiation effects such as Total Ionizing Dose and Single Event Effects are translated into architectural constraints early in the design process. A closed validation loop links modelling with experimental radiation testing of dedicated test structures, improving predictability and reducing early-stage design iterations.

Staged Validation and Strategic Impact

The project applies a staged validation approach. Dedicated radiation test structures are designed and fabricated using European foundry processes, then experimentally characterized at qualified facilities under coordination and supervision by NLR. Measured radiation behavior is fed back into the workflow to refine modeling and architectural decisions. This approach increases first-pass success probability and strengthens Dutch and European strategic autonomy in high-reliability semiconductor technologies. The results are validated through a Laser Satellite Communication (LSC) case study, demonstrating the workflow on a representative space application.
