  • Patent number: 6458630
    Abstract: 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 k nanopore/nanofoam dielectric material adjacent the conductive line ends.

  • Patent number: 6455914
    Abstract: 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.

  • Publication number: 20020132378
    Abstract: A wafer level system for producing burn-in, voltages screen, and reliability evaluations which are to be performed on all wafers simultaneously without necessitating the probe contacting of any wafer during burn-in/stress. Also provided is a method for implementing the wafer level product burn-in/screen, and semiconductor reliability evaluations on semiconductor chips pursuant to the wafer level system. Pursuant to a preferred aspect all chips of a wafer are stressed simultaneously without having a probe physically contact any chip during the stress procedure. This concept can be applied to burn-in of product wafers, voltage screen of product wafers, and reliability evaluations of various failure mechanisms.

  • Patent number: 6375159
    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.
