In radiation therapy, precision is critical, and the control systems within linear accelerators must remain reliable to administer accurate doses to patients. Any malfunction due to radiation exposure could lead to severe treatment errors, making radiation-resistant electronics a necessity in such applications. Additionally, electronic systems in sterilization equipment, which use radiation to eliminate bacteria and pathogens, benefit from rad-hard components to maintain efficiency and longevity.
The global segmentation, based on manufacturing technique, includes radiation-hardening by process (RHBP) and radiation-hardening by design (RHBD). The radiation-hardening by design (RHBD) segment captured 58.96% market share in 2024 due to its focus on circuit-level and architectural modifications to improve a component’s resistance to radiation effects without altering the underlying manufacturing process. This technique involves implementing error correction codes (ECC), triple modular redundancy (TMR), latch-up protection, and hardened circuit layouts to minimize the impact of single-event effects (SEEs) and total ionizing dose (TID). RHBD improves the component’s resilience through intelligent circuit design and software-based fault tolerance. This makes RHBD a more cost-effective solution for applications where moderate radiation tolerance is sufficient, such as low Earth orbit (LEO) satellites, commercial space missions, and some defense electronics.
The radiation-hardening by process (RHBP) segment growth is driven by the modification of the semiconductor fabrication process to enhance a component’s resistance to radiation-induced damage. The method focuses on altering material properties, doping techniques, and insulation layers to minimize the effects of radiation exposure. Advanced techniques include the use of silicon-on-insulator (SOI) technology, hardened gate oxides, and selective doping to reduce leakage currents and mitigate total ionizing dose (TID) effects. RHBP is particularly effective in environments where prolonged radiation exposure is a concern, such as deep-space missions, nuclear power plants, and high-altitude defense applications. Components developed using this technique exhibit higher reliability and longevity in extreme radiation environments as RHBP enhances the physical properties of a semiconductor.
