Abstract
The present disclosure is directed to a semiconductor chip having protection against focused ion beam (FIB) attack. The semiconductor chip includes a conductor structure connected to a dielectric material, which has the property of giving rise, when ions are introduced, to an electrical conductivity which is sufficient for circuit-related connection of the conductors. When such a dielectric material is irradiated with ions, its electrical conductivity increases so that the electronic circuit integrated in the chip registers the electrical connection generated in this way between the conductors adjoining the dielectric material. Organic materials having a π-system are suitable for use as the dielectric material.
