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