Abstract: A method for detecting an attack, such as by laser, on an electronic microcircuit from a backside of a substrate includes forming the microcircuit on the semiconductor substrate, the microcircuit comprising a circuit to be protected against attacks, forming photodiodes between components of the circuit to be protected, forming a circuit for comparing a signal supplied by each photodiode with a threshold value, and forming a circuit for activating a detection signal when a signal at output of one of the photodiodes crosses the threshold value.
