Abstract

A system and method for evaluating the reliability of semiconductor die packages are configured to sort a plurality of semiconductor dies with a Known Good Die (KGD) subsystem based on a comparison of an inline part average testing (I-PAT) score of each of the plurality of semiconductor dies to a plurality of I-PAT score thresholds, where the semiconductor die data includes the I-PAT score for each of the plurality of semiconductor dies, where the I-PAT score represents a weighted defectivity of the corresponding semiconductor die. The semiconductor dies may be filtered to remove at-risk semiconductor dies prior to sorting. The semiconductor die data may be received from a plurality of semiconductor die supplier subsystems. The KGD subsystem may transmit semiconductor die reliability data about the sorted plurality of semiconductor dies to a plurality of semiconductor die packager subsystems.
