发明名称 On-chip electromigration monitoring
摘要 A method is provided for monitoring interconnect resistance within a semiconductor chip assembly, A semiconductor chip assembly can include a semiconductor chip having contacts exposed at a surface of the semiconductor chip and a substrate having exposed terminals in conductive communication with the contacts. A plurality of monitored elements of the semiconductor chip can include conductive interconnects, each interconnecting a respective pair of nodes of the semiconductor chip through wiring within the semiconductor chip. In an example of such method, a voltage drop across each monitored element is compared with a reference voltage drop across a respective reference element on the semiconductor chip at a plurality of different times during a lifetime of the semiconductor chip assembly. In that way, it can be detected when a resistance of such monitored element is over threshold. Based on a result of such comparison, a decision can be made whether to indicate an action condition.
