Patent ID: 7701035

Claim:
A laser fuse structure, comprising: first and second conductive supporting elements located at a first metal level of an integrated circuit (IC) chip in a spaced-apart relationship; multiple conductive fusible links located at the first metal level between the first and second conductive supporting elements for directly connecting same, wherein the multiple conductive fusible links are arranged in parallel and are spaced apart from one another by a distance of not more than 2 μm, wherein each of the multiple conductive fusible links have the same dimensions and comprise a length of at least about 12 μm, a thickness of not more than about 1.5 μm, and a width of not more than about 1 μm, in which the multiple conductive fusible links have a current capacity of not less than 30 mA; first and second connection elements located at a second, different metal level of the IC chip, wherein the first and second conductive support elements are respectively connected to said first and second connection elements by first and second via stacks that each comprises one or more conductive vias extending between the first and second metal levels; and first and second metal lines located at the first metal level, wherein the first and second connection elements are respectively connected to said first and second metal lines by third and fourth via stacks that each comprises one or more conductive vias extending between the first and second metal levels.
