During read, a read bias is applied that is sufficient to cause formation of a transient bridge in the second dielectric layer, and make a conductive path through the cell if the bridge is present in the first dielectric layer. If the bridge is not present in the first dielectric layer during the read, then the conductive path is not formed. Upon removal of the read bias voltage any the conductive bridge formed in the second dielectric layer is destructed while the conductive bridge in the corresponding other first dielectric layer, if any, remains.

  • Patent number: 8487404
    Abstract: The present invention provides fuse patterns and a method of manufacturing the same. According to the present invention, an insulating layer and a contact plug are filled between fuse patterns which are formed to have their ends broken and are isolated from each other. In case of a fail cell, the insulating layer is broken owing a difference in an electrical bias (current or voltage) between a metal wire and the fuse patterns, and a short is generated between the fuse patterns. Accordingly, embodiments avoid damage to a semiconductor substrate associated with a conventional fuse repair method employing laser energy, and the area of a fuse box can be reduced.

  • Publication number: 20130176073
    Abstract: A BEOL e-fuse is disclosed which reliably blows in the via and can be formed even in the tightest pitch BEOL layers. The BEOL e-fuse can be formed utilizing a line first dual damascene process to create a sub-lithographic via to be the programmable link of the e-fuse. The sub-lithographic via can be patterned using standard lithography and the cross section of the via can be tuned to match the target programming current.

  • Publication number: 20130168806
    Abstract: A high programming efficiency electrical fuse is provided utilizing a dual damascene structure located atop a metal layer. The dual damascene structure includes a patterned dielectric material having a line opening located above and connected to an underlying via opening. The via opening is located atop and is connected to the metal layer. The dual damascene structure also includes a conductive feature within the line opening and the via opening. Dielectric spacers are also present within the line opening and the via opening. The dielectric spacers are present on vertical sidewalls of the patterned dielectric material and separate the conductive feature from the patterned dielectric material. The presence of the dielectric spacers within the line opening and the via opening reduces the area in which the conductive feature is formed. As such, a high programming efficiency electrical fuse is provided in which space is saved.

    Abstract: A three-dimensional integrated circuit (3D-IC) includes a stack of semiconductor wafers, each of which includes a substrate and a device layer. Programmable components, such as memory arrays or logic circuits, are formed within the device layers. Some of the programmable components are redundant, and can be substituted for defective components by programming passive memory elements in a separate conductive layer provided for this purpose. The separate conductive layer is devoid of active devices, and is therefore relatively reliable and inexpensive.

  • Patent number: 8471296
    Abstract: A method forms an eFuse structure that has a pair of adjacent semiconducting fins projecting from the planar surface of a substrate (in a direction perpendicular to the planar surface). The fins have planar sidewalls (perpendicular to the planar surface of the substrate) and planar tops (parallel to the planar surface of the substrate). The tops are positioned at distal ends of the fins relative to the substrate. An insulating layer covers the tops and the sidewalls of the fins and covers an intervening substrate portion of the planar surface of the substrate located between the fins. A metal layer covers the insulating layer. A pair of conductive contacts are connected to the metal layer at locations where the metal layer is adjacent the top of the fins.
