ABSTRACT:
An ohmic resistance is present between two parts of a conductor layer so that the size of the ohmic resistance can be ascertained and/or a semiconductor region is present in or on a layer forming the dielectric. The conductor layer is structured into a gate contact, a source contact, and a drain contact so that a transistor function or switching function is possible in the semiconductor region. Such a configuration allows an attempt to analyze the circuit integrated in the chip to be detected.
