摘要： A structure and method for providing an antifuse which is closed by laser energy with an electrostatic assist. Two or more metal segments are formed over a semiconductor structure with an air gap or a porous dielectric between the metal segments. Pulsed laser energy is applied to one or more of the metal segments while a voltage potential is applied between the metal segments to create an electrostatic field. The pulsed laser energy softens the metal segment, and the electrostatic field causes the metal segments to move into contact with each other. The electrostatic field reduces the amount of laser energy which must be applied to the semiconductor structure to close the antifuse.

摘要： A method and structure for fabricating a laser fuse and a method for programming the laser fuse. The laser fuse includes a first dielectric layer having two vias filled with a first self-passivated electrically conducting material. A fuse link is on top of the first dielectric layer. The fuse link electrically connects the two vias and includes a second material having a characteristic of changing its electrical resistance after being exposed to a laser beam. Two mesas are over the fuse link and directly over the two vias. The two mesas each include a third self-passivated electrically conducting material. The laser fuse is programmed by directing a laser beam to the fuse link. The laser beam is controlled such that, in response to the impact of the laser beam upon the fuse link, the electrical resistance of the fuse link changes but the fuse link is not blown off. Such electrical resistance change is sensed and converted to digital signal.

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： Semiconductor chip structures are provided with embedded thermal conductors for removing heat from one or more electrically conductive circuit members thereof, wherein the circuit members are formed on one or more dielectric layers above a substrate, each layer having a low dielectric constant and a low thermal conductivity. One or more cooling posts, for example, multiple thermally conductive plugs, are selectively disposed within the semiconductor chip structure adjacent to one or more electrically conductive members and thermally coupled thereto so that heat produced by the members is transferred into and through the cooling posts for forwarding to the substrate and/or to an upper surface of the semiconductor chip structure. The backside of the substrate has a thermal sink thermally coupled thereto and electrically isolated from the substrate. The thermal sink includes one or more thermally conductive via structures embedded within the substrate and aligned to thermally contact to the cooling posts disposed above the substrate.

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： An adjustable self aligned low capacitance integrated circuit air gap structure comprises a first interconnect adjacent a second interconnect on an interconnect level, spacers formed along adjacent sides of the first and second interconnects, and an air gap formed between the first and second interconnects. The air gap extends above an upper surface of at least one of the first and second interconnects and below a lower surface of at least one of the first and second interconnects, and the distance between the spacers defines the width of the air gap. The air gap is self-aligned to the adjacent sides of the first and second interconnects.
