Patent ID: 7122899

Claim:
A semiconductor device, comprising: an electronic device selected from at least one of the group consisting of an active device and an integrated circuit; a layer structure applied to said electronic device, said layer structure having: a layer of a dielectric; at least one conductor layer having at least one structured portion; at least one configuration selected from the group consisting of; a multi-layered resistance network; a resistance network characteristic of an individual chip or a respective chip type; a resistance network formed within a polymer film by doping atoms of varying concentrations; and a material having a semiconductor region formed therein, said material having at least partly semiconducting properties, said material disposed at said layer of dielectric, said semiconductor region performing a function of at least one of an active part and a switching part of said electronic device; and said electronic device checking resistance values of said layer structure and at least one of monitoring intactness of said layer structure and establishing an identity of said layer structure based upon a check of said resistance values of said layer structure.
