摘要

Cosmic-ray soft errors from ground level to aircraft flightnaltitudes are caused mainly by neutrons. We derived an empirical modelnfor estimation of soft error rate (SER). Test circuits were fabricatednin a standard 0.6-Μm CMOS process. The neutron SER dependence on thencritical charge and supply voltage was measured. Time constants of thennoise current were extracted from the measurements and compared withndevice simulations in three dimensions. The empirical model wasncalibrated and verified by independent SER measurements. The model isncapable of predicting cosmic-ray neutron SER of any circuit manufacturednin the same process as the test circuits. We predicted SER of a staticnmemory cell
