Abstract
One embodiment of the present invention relates to a scribe seal integrity detector. In this embodiment a scribe seal integrity detector is formed in an integrated circuit chip die. The scribe seal integrity comprises a scribe seal structure that extends along at least a portion of the periphery of the integrated chip die and a detector test structure. The detector test structure and the scribe seal form an electrical system configured to be accessed for a monitoring of one or more electrical parameters to determine and characterize scribe seal integrity of the integrated circuit chip die. The results of the electric measurements are analyzed for statistically relevant reliability characterization. Other methods and circuits are also disclosed.
