Abstract
An edge crack monitoring system for an integrated circuit provided on a die, comprises a conductive trace comprising at least a first conductive path for allowing current in a first direction, and a second adjacent conductive path for allowing current in a second direction opposite to the first direction. Both adjacent conductive paths form at least one loop surrounding a semiconductor device on a die. The arrangement of the trace is adapted to provide compensation of EM interferences. The trace comprises two terminals being connectable to a detection circuit for detecting damages by generating a fault signal upon detection of disruption of the conductive trace due to a damage. The conductive trace comprises high resistance portions with a resistance of at least 1 kΩ, adapted for reducing self-resonance.
