Abstract
Fuses and interconnects are fabricated by applying a metallic layer on a substrate and a fusible layer on the metallic layer. Portions of the fusible layer are removed to define discrete fuse elements having a necked portion. Portions of the metallic layer are removed to define interconnects. A portion of the metallic layer coextensive with the necked portion of the fuse elements is removed by selective side etching to form tapering portions separated by a gap without etching of the interconnects. The interconnects are protected from side etching by a separate mask layer or a mask layer used to form the interconnects may be heated to flow down over the sides of the interconnects.
