Abstract
A laser detection device can be used to protect an integrated circuit. The device includes a detection cell having a buried channel of a first conductivity type extending in a substrate of the integrated circuit. The substrate is of a second conductivity type. The detection cell also has a first electrical connection coupling a first point in the buried channel to a supply voltage rail, and a second electrical connection coupled to a second point in the buried channel. A detection circuit is coupled to the second point in the buried channel via the second electrical connection and adapted to detect a fall in the voltage at the second point.
