Abstract
Disclosed embodiments include an integrated circuit having a semiconductor substrate with insulator layers and conductor layers overlying the semiconductor substrate. A scribe region overlying the semiconductor substrate and a periphery of the integrated circuit includes a crack arrest structure and a scribe seal. The crack arrest structure provides first vertical conductor structure that surrounds the periphery of the integrated circuit. The scribe seal is spaced from and surrounded by the crack arrest structure and provides a second vertical conductor structure. The scribe seal includes first and second vias spaced from each other and connected to one of the conductor layers. The first via is a trench via and the second via is a stitch via, with the second via being located closer to the crack arrest structure than the first via.
