Abstract :
Simulations are used to characterize the single event transient current and voltage waveforms in deep submicron CMOS integrated circuits. Results indicate that the mechanism controlling the height and duration of the observed current plateau is the redistribution of the electrostatic potential in the substrate following a particle strike. Quantitative circuit and technology factors influencing the mechanism include restoring current, device sizing, and well and substrate doping.
