Single event upset (SEU) induced by secondary cosmic-ray neutrons is one of the causes of non-destructive faults (the so-called soft errors) in microelectronics. We have proposed a method to estimate the terrestrial soft error rates (SERs) based on simulation coupled with one-time neutron irradiation testing which can be applied to various kinds of neutron sources. The validity of our method has been investigated for 65-nm bulk SRAMs with the measured data using various neutron sources. This result will be reviewed on the organized session of the 67th Space Sciences and Technology Conference.
