    • Trench anti-fuse structures, design structures embodied in a machine readable medium for designing, manufacturing, or testing a programmable integrated circuit. The anti-fuse structure includes a trench having a plurality of sidewalls that extend into a substrate, a doped region in the semiconductor material of the substrate proximate to the sidewalls of the trench, a conductive plug in the trench, and a dielectric layer on the sidewalls of the trench. The dielectric layer is disposed between the conductive plug and the doped region. The dielectric layer is configured so that a programming voltage applied between the doped region and the conductive plug causes a breakdown of the dielectric layer within a region of the trench. The trench sidewalls are arranged with a cross-sectional geometrical shape that is independent of position between a bottom wall of the deep trench and a top surface of the substrate.
