Abstract :
Heavy-ion broad-beam experiments on a 130 nm CMOS technology have shown anomalously-short single-event transient pulse widths. 3-D TCAD mixed-mode modeling in 90 nm and 130 nm bulk CMOS has identified a mechanism for simultaneous charge collection on proximal circuit nodes interacting in a way as to truncate, or ¿quench,¿ a propagated voltage transient, effectively limiting the observed SET pulse widths at high LET. This quenching mechanism is described and analyzed.
