Abstract
A design structure for an on-chip real-time moisture detection circuitry for monitoring ingress of moisture into an integrated circuit chip during the operational lifetime of the chip. The moisture detection circuitry includes one or more moisture-sensing units and a common moisture monitor for monitoring the state of each moisture-sensing units. The moisture monitor can be configured to provided a real-time moisture-detected signal for signaling that moisture ingress into the integrated circuit chip has occurred.
