Abstract: We examine use of proton SEE data to constrain heavy -ion SEE susceptibility. We discuss limitations due to short range proton recoils and develop an approach for using proton data to constrain on device sensitive volumes. Use of Proton SEE Data as a Proxy for Bounding Heavy-Ion SEE Susceptibility Ray Ladbury 1 and Jean-Marie Lauenstein 1 and Kathryn P. Hayes 2 Conclusions We have examined the effect on device SV geometry on theconclusions that can be drawn from proton SEE data for heavy-ion SEEsusceptibility. We find that for devise SV with depths greater than about 5microns, charge generation by recoil ions from proton-ion collisions tendsto be limited by the ion’s range rather than its LET. This means that protondata place very weak constraints on heavy-ion induced SEL. Similarconsiderations apply for SEGR and SEB. However, dependence on ionangle of incidence and ion species for these failure modes mean thatgeneralizing from proton data to heavy-ion susceptibility is risky.We also propose a generalized linear model approach for using protonSEE data to bound heavy-ion SEE susceptibilities that allows data forseveral proton energies to be combined to draw more reliable conclusionsabout device SV geometries from proton data.
