Abstract
We report low-energy proton and low-energy alpha particle SEE data on a 32 nm SOI CMOS SRAM that demonstrates the criticality of using low-energy protons for SEE testing of highly-scaled technologies. Low-energy protons produced a significantly higher fraction of multi-bit upsets relative to single-bit upsets when compared to similar alpha particle data. This difference highlights the importance of performing hardness assurance testing with protons that include energy distribution components below 2 MeV. The importance of low-energy protons to system-level single-event performance is based on the technology under investigation as well as the target radiation environment.
