Abstract
A fuse structure includes a substrate, a fuse conductive trace disposed closer to a first chip surface than to a second chip surface facing away from the first chip surface, a metallization layer on the substrate disposed on a side of the fuse conductive trace facing away from the first chip surface, and a planar barrier multilayer assembly disposed between the fuse conductive trace and the metallization layer and including multiple barrier layers of different materials, wherein the fuse conductive trace, the metallization layer and the barrier multilayer assembly are arranged such that when cutting the fuse conductive trace and the barrier multilayer assembly, a first area of the metallization layer is electrically isolated from a second area of the metallization layer.
