Abstract
The invention relates to a method for analyzing an integrated circuit, including a step for applying laser radiation at a point on the surface of the circuit, a step for exciting the circuit thus subjected to laser radiation by applying an electrical excitation signal, a step for collecting the response of the circuit to the excitation, the circuit being subjected to laser radiation, and a step for measuring the phase difference between the response to the excitation of the circuit subjected to laser radiation and a reference response of the circuit in the absence of laser radiation applied to the circuit. The invention also relates to an associated observation method and installation.
