Abstract
An integrated circuit, including: a semiconductor substrate of a first conductivity type; a plurality of regions of the first conductivity type vertically extending from the surface of the substrate, each of the regions being laterally delimited all along its periphery by a region of the second conductivity type; and a device for detecting a variation of the substrate resistance between each region of the first conductivity type and an area for biasing the substrate to a reference voltage.
