Claim:
1. A semiconductor die, comprising: an integrated circuit (IC); and an edge assurance structure arranged around an edge of the integrated circuit, the edge assurance structure having a plurality of v-shaped structures configured to detect an existence of a crack in the semiconductor die, wherein the edge assurance structure includes a gap between a first v-shaped structure and a second v-shaped structure of the plurality of v-shaped structures so that the first and second v-shaped structures are electrically isolated from each other to enable resistance testing of the edge assurance structure to detect the existence of a crack in the semiconductor die, and wherein the IC includes a first IC pad and a second IC pad, the first IC pad electrically connected to a metal layer of the first v-shaped structure and the second IC pad electrically connected to a metal layer of the second v-shaped structure; and an additional metal layer that electrically connects the edge assurance structure to a seal ring that surrounds the IC.
