Abstract
Embodiments of the disclosure provide a system for detecting and monitoring a crack in an integrated circuit (IC), including: at least one electrically conductive perimeter line (PLINE) extending about, and electrically isolated from, a protective structure formed in an inactive region of the IC, wherein an active region of the IC is enclosed within the protective structure; a circuit for sensing a change in an electrical characteristic of the at least one PLINE, the change in the electrical characteristic indicating a presence of a crack in the inactive region of the IC; and a connecting structure for electrically coupling each PLINE to the sensing circuit.
