Ionizing radiation can produce in electronic components some perturbations called “Single Event Effects”, or SEE. Using a pulsed laser, it is possible to reproduce the electrical behavior due to this phenomenon by locally injecting electric charges in the active area. The correlation with the laser position can therefore produce a map of the sensitive areas of the silicon die.
