Patent ID: 8293581

Claim:
A method of manufacturing, comprising: fabricating an active region of a semiconductor die so that the active region has at least one substantially right-angle corner; fabricating a scribe structure around the active region so that the scribe structure includes at least one fillet, said fillet contacting the corner at the vertex of the right-angle, the scribe structure having a non-uniform cross-section; and fabricating walls of the scribe structure with segments, such that the segments in the resulting wall comprise vias and conductor layers interspersed with interlevel dielectric material, comprising interlevel dielectric layers, wherein the walls of the at least one fillet of the scribe structure are fabricated from a plurality of rows of separate segments and the plurality of rows of separate segments of the at least one fillet is greater than the plurality of rows of separate segments in the walls of the scribe structure not forming part of the at least one fillet.
