Abstract
An interconnect structure with an interconnect stack consisting of a number of alternating conductive planes and insulating planes. The stack has a number of conductive elements such as conductive vias extend generally normal to the conductive insulating planes of the stack and a number of profiled apertures having geometrical shapes such that they define fuse links in one or more of the conductive planes. The fuse links have a steeply narrowed waist, such that a fusing current I passing through the fuse link produces a fused break substantially at the steeply narrowed waist. Profiled apertures can also be used to define anti-fuse links in interconnect structures such that passing an anti-fusing current I through the anti-fuse link produces a fused joint substantially at the steeply narrowed waist.
