Abstract
A radiant-energy configurable fuse structure and array are provided in which the fuse body of the fuse is wider than the fuse connection terminals. The fuse body can be circular or polygonal to capture more of the radiant energy from a targeting beam, which reduces the energy required to blow the fuse. As a result, unrelated circuit elements and patterned lines can be placed closer together in a laser fuse array, thereby increasing the packing density of such arrays.
