Abstract

The results of laser single-event effect (SEE) simulation in digital potentiometer AD8400, using the two-photon absorption (TPA) of tightly focused femtosecond 1200 nm laser radiation are presented. Comparative measurements obtained by the single-photon absorption (SPA) of picosecond 1064 nm laser radiation in the same device revealed the improved 3D-spatial resolution of TPA compared to SPA-based pulsed laser testing. The effective depth of single event latchup (SEL) sensitive layer estimation was calculated from experimental results.
