Abstract
An integrated circuit including a plurality of first semiconductor strips of a first conductivity type and of second semiconductor strips of a second conductivity type arranged in alternated and contiguous fashion on a region of the second conductivity type, including for each of the first strips: a plurality of bias contacts; for each bias contact, a switch capable of applying a potential on the bias contact; two detection contacts arranged at the ends of the first strip; and a detection circuit having its activation causing the turning off of the switches and the comparison with a threshold of the resistance between the detection contacts.
