Abstract: A method for fabricating a dual damascene coper interconnect which electrically contacts a damascene tungsten wiring level (190) comprising forming a first layer on a semiconductor substrate, a silicon nitride layer (140) on the first layer, and a silicon dioxide layer (150) on the silicon nitride layer. The first layer includes damascene tungsten interconnect regions separated by electrically insulating material. A continuous space (630) is formed by etching two contact throughs (910) through the silicon dioxide and silicon nitride layers to expose damascene tungsten interconnect regions, and by etching a top portion of the silicon dioxide layer between the two contact throughs. A reduced-height portion of the silicon dioxide layer remains between the two contact troughs. The continuous space is filled with damascene copper. The resulting dual damascene copper interconnect electrically contacts the exposed damascene tungsten interconnect regions.

Abstract: A method and structure that provides a battery (420) within an integrated circuit for providing voltage to low-current electronic devices (900) that exist within the integrated circuit. The method includes Front-End-Of-Line (FEOL) processing for generating a layer of electronic devices (900) on a semiconductor wafer (402), followed by Back-End-Of-Line (BEOL) integration for wires the electronic devices together to form completed electrical circuits of the integrated circuit. The BEOL integration includes forming a multilayered structure of wiring levels on the layer of electronic devices. Each wiring level includes conductive metallization (e.g., metal-plated vias, conductive wiring lines, etc.) embedded in insulative material. The battery (420) is formed during BEOL integration within one or more wiring levels, and the conductive metallization (432,434,442,444) conductively couples positive (424) and negative (422) terminals of the battery to the electronic devices (900). The battery (420) may have several different topologies relative to the structural and geometrical relationships among the battery electrodes and electrolyte. Multiple batteries may be formed within one or more wiring levels, and may be conductively coupled to the electronic devices. The multiple batteries may be connected in series or in parallel.

Abstract: A method and structure for fabricating a dual damascene copper interconnect which electrically contacts a damascene tungsten wiring level. The method forms a first layer on a semiconductor substrate, a silicon nitride layer on the first layer, and a silicon dioxide layer on the silicon nitride layer. The first layer includes damascene tungsten interconnect regions separated by insulative dielectric material. A continuous space is formed by etching two contact troughs through the silicon dioxide and silicon nitride layers to expose damascene tungsten interconnect regions, and by etching a top portion of the silicon dioxide layer between the two contact troughs. A reduced-height portion of the silicon dioxide layer remains between the two contact troughs. The continuous space is filled with damascene copper. The resulting dual damascene copper interconnect electrically contacts the exposed damascene tungsten interconnect regions.
