METAL FUSE BY TOPOLOGY

Embodiments of the present disclosure describe techniques and configurations for overcurrent fuses in integrated circuit (IC) devices. In one embodiment, a device layer of a die may include a first line structure with a recessed portion between opposite end portions and two second line structures positioned on opposite sides of the first line structure. An isolation material may be disposed in the gaps between the line structures and in a first recess defined by the recessed portion. The isolation material may have a recessed portion that defines a second recess in the first recess, and a fuse structure may be disposed in the second recess. Other embodiments may be described and/or claimed. Figure 1A
