Estimating the term…
A prognostic circuit of EM failure for IC is disclosed, which includes a current monitoring module, the current monitoring module includes a current output module electrically connected with a monitoring metal wire, and one or more conductive metals covered by an oxide layer and electrically insulated with the monitoring metal wire, the current output module includes at least one current source, the conductive metal is electrically connected with the output port of the current monitoring module, and the monitoring metal wire is surrounded by the conductive metal. The above prognostic circuit can give a warning for short-circuit failure caused by a whisker created by EM. Meanwhile, the prognostic circuit of the present disclosure can also be added a resistance warning, and it can indicate the failure of the resistance increased by EM and the short circuit caused by whisker, so as to greatly increase the warning efficiency of the EM.
