    Abstract: A high laser absorption copper fuse can minimize the laser energy needed to delete the fuse portion of the conductor. Significantly, this type of fuse structure would allow for formation of copper fuses that can be deleted with appreciably less incident energy, mainly by increasing the absorption of the fuse link at the given incident laser energies. A metal wiring line contains a fuse link segment wherein the fuse link segment is composed of a stack of at least two metals. The underlayer material in the stack of metals is the primary electrical copper conductor, and the overlayer metal, also an electrical conductor, primarily tungsten or titanium-tungsten in composition, has predetermined thickness and optical properties chosen such that the combination of the overlayer metal with the underlayer metal provides for high absorption characteristics to incident infrared energy. Fabrication methods for providing overlaying material to the entire fuse link line, or to selective portions of the fuse link line are presented.

    Abstract: The act of blowing an unpassivated electrical fuse (for example, fuse 405) using a laser can result in the splattering of the fuse material and result in electrical short circuits. A blast barrier (for example blast barrier 406) formed around an area of the fuse that is blown by the laser helps to contain the splattering of the fuse material. The blast barrier may be formed from the same material as the fuses themselves and therefore, can be created in the same fabrication step.

    Abstract: A structure and associated method for protecting an electrical structure (25) during a fuse link deletion by focused radiation (52). The structure (1 ) comprises a fuse element (2), a protection plate (10), a first dielectric layer (14), and a second dielectric layer (4). The structure (1) is formed within a semiconductor device (5). The protection plate (10) is formed within the first dielectric layer (14) using a damascene process. The second dielectric layer (4) is formed over the protection plate (10) and the first dielectric layer (14). The fuse element (2) is formed over the second dielectric layer (4). The fuse element (2) is adapted to be cut with a laser beam (52). The dielectric constant of the second dielectric layer (4) is greater than the dielectric constant of the first dielectric layer (14). The protection plate (10) is adapted to shield the first dielectric layer (14) from energy from the laser beam (52).
