    摘要： A fusible link for a semiconductor device comprises an insulating substrate and a conductive line pair on the surface of the insulating substrate, with the conductive line pair having spaced ends. A polymer is disposed over the insulating substrate and between the conductive line pair ends. The polymer is capable of being changed from a non-conductive to a conductive state upon exposure to an energy beam. Preferably, the polymer comprises a polyimide, more preferably, a polymer/onium salt mixture, most preferably, a polyaniline polymer doped with a triphenylsufonium salt. The link may further comprise a low &kgr; nanopore/nanofoam dielectric material adjacent the conductive line ends.

    摘要： A structure and method of fabricating a metallization fuse line is disclosed. The structure can be formed on a semiconductor substrate, including an insulator structure formed on the substrate, the insulator structure having an upper layer and a lower layer, the upper being thinner than the lower, the insulator structure having a plurality of openings of varying depth, and a metal structure inlaid in the insulator structure, the metal structure having first and second portions and a third portion there between that is substantially more resistive than the first and second portions, the third portion having a thickness substantially- similar to the thickness of the upper layer of the insulator structure. The upper layer includes a nitride, the lower layer includes an oxide and the metal structure includes copper. The fuse structure allows formation of “easy to laser delete” thin metal fuses within segments of thick metal lines. This applies to wiring layers formed from “high” melting temperature metals and those defined using a damascene process. For example, copper back end of line (Cu BEOL) damascene wiring, as used with CMOS can use the invention. The technique achieves high yield fusing for technologies that use thick wiring layers. The structure separates the thickness of the fuse segment from the remainder of the wiring line. The structure can be used with very thick, e.g., >1.2&mgr; wiring and very thin, e.g.,

    摘要： A structure and method of fabricating a semiconductor corrosion resistant metal fuse line including a refractory liner which can also act as a resistor is disclosed. Fabrication is accomplished using damascene process. The metal structure can be formed on a semiconductor substrate including a first portion including a first layer and a second layer, the first layer having higher resistivity than the second layer, the second layer having horizontal and vertical surfaces that are in contact with the first layer in the first portion, and a second portion coupled to the first portion, the second portion being comprised of the first layer, the first layer not being in contact with the horizontal and vertical surfaces of the second layer in the second portion. The metal structure can be used as a corrosion resistant fuse. The metal structure can also be used as a resistive element. The high voltage tolerant resistor structure allows for usage in mixed-voltage, and mixed signal and analog/digital applications. The resistor element has low capacitance, low skin effect, high linearity, a high melting temperature, and a high critical current to failure. The resistor structure can be formed on the walls of a dielectric trough. The structure can be applied to circuit applications such as an ESD network, an RC-coupled MOSFET, a resistor ballasted MOSFET and others. The resistors can be in series with the MOSFET or other structures.

    摘要： 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.
