Abstract
A method of making a fuse and a fuse, together with systems and integrated circuits where the fuse provides benefits, are described. A fuse comprising a conductive material is formed on a substrate. A series of dielectric layers having a composite thickness is formed on the substrate and the fuse. The series of dielectric layers serves to insulate a series of conductive layers from each other. The conductive layers are disposed above portions of the substrate. An opening is formed extending through a passivation layer and the series of dielectric layers. The opening exposes a portion of the fuse. Another dielectric layer is formed on the fuse and the fuse may thereafter be programmed by directing a laser beam onto the fuse through the opening.
