    摘要: Voltage programmable anti-fuse structures and methods are provided that include at least one conductive material island atop a dielectric surface that is located between two adjacent conductive features. In one embodiment, the anti-fuse structure includes a dielectric material having at least two adjacent conductive features embedded therein. At least one conductive material island is located on an upper surface of the dielectric material that is located between the at least two adjacent conductive features. A dielectric capping layer is located on exposed surfaces of the dielectric material, the at least one conductive material island and the at least two adjacent conductive features. When the anti-fuse structure is in a programmed state, a dielectric breakdown path is present in the dielectric material that is located beneath the at least one conductive material island which conducts electrical current to electrically couple the two adjacent conductive features.

    摘要: 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.

    摘要: A method is provided that includes first etching a substrate according to a first mask. The first etching forms a first etch feature in the substrate to a first depth. The first etching also forms a sliver opening in the substrate. The sliver opening may then be filled with a fill material. A second mask may be formed by removing a portion of the first mask. The substrate exposed by the second mask may be etched with a second etch, in which the second etching is selective to the fill material. The second etching extends the first etch feature to a second depth that is greater than the first depth, and the second etch forms a second etch feature. The first etch feature and the second etch feature may then be filled with a conductive metal.
