Abstract

An exemplary method includes forming a fuse structure and forming a first cathode connector and a second cathode connector over the fuse structure. The fuse structure includes an anode, a cathode, and a fuse link extending between and connecting the anode and the cathode. The fuse link has a width defined between a first edge and a second edge, which extend a length of the fuse link. The cathode includes a central region defined by a first longitudinal axis and a second longitudinal axis extending respectively from the first edge and the second edge. The first cathode connector and the second cathode connector are equidistant respectively to the fuse link, the first cathode connector does not intersect the first longitudinal axis, and the second cathode connector does not intersect the second longitudinal axis, such that the central region is free of the first cathode connector and the second cathode connector.
