Abstract
A method and installation for analyzing an integrated circuit. The method includes, for a plurality of surface points of the integrated circuit, the following steps: applying a laser radiation, in one point of the surface of the integrated circuit; exciting the circuit; collecting the response of the circuit to the excitation; calculating the propagation time intervening between the excitation time and the response-collecting time; and creating an image of the integrated circuit showing a value representing the propagation time at each point of laser radiation application.
