Abstract
A semiconductor device comprises a substrate provided with a doping of a first type, on which an electronic circuit is provided surrounded by a circuit portion of the substrate provided with a doping of a second type; at least one pad for connecting the electronic circuit to an external device outside the substrate, surrounded by a pad portion provided with a doping of the second type; a sensing device comprising a sensor portion of the substrate provided with a doping of the first type, for sensing a parameter forming a measure for a local electrical potential of the substrate; and an evaluation unit connected to the sensing device, for providing an evaluation signal based on a difference between the parameter and a reference value.
