摘要: A semiconductor structure comprising a fuse/resistor structure over a functional layer having a substrate. The fuse/resistor structure includes a via, a first interconnect layer, and a second interconnect layer. The via is over the functional layer and has a first end and a second end vertically opposite the first end, wherein the first end is bounded by a first edge and a second edge opposite the first edge and the second end is bounded by a third edge and a fourth edge opposite the third edge. The first interconnect layer includes a first metal layer running horizontally and contacting the first end and completely extending from the first edge to the second edge. The second interconnect layer includes a second metal layer running horizontally and contacting the second end of the via and extending past the third edge but reaching less than half way to the fourth edge.
