Each integrated circuit die includes plurality of active areas; a plurality of insulator layers overlying the active areas; a plurality of conductor layers interspersed with and separated by ones of the insulator layers; and a passivation layer overlying a top portion of the uppermost one of the conductor layers. A scribe seal in a scribe region surrounds the periphery of the integrated circuit dies, the scribe seal covered by the passivation layer; and a crack arrest structure is located surrounding and spaced from the scribe seal, and including an opening in the passivation layer that extends to and exposes the upper surface of the crack arrest structure.
