Abstract
A semiconductor structure includes a semiconductor substrate, one or more interconnect layers provided over the substrate and a circuit. The circuit includes a plurality of circuit elements formed at the substrate and a plurality of electrical connections provided in the one or more interconnect layers. A die seal is provided in the one or more interconnect layers. A die seal leakage detection material is arranged in the one or more interconnect layers between the die seal and the plurality of electrical connections. The die seal provides a protection of the die seal leakage detection material from moisture if the die seal is intact. The die seal leakage detection material is adapted for providing a detectable modification of the circuit after an exposure of the die seal leakage detection material to moisture.
