摘要： 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.

摘要： An anti-fuse structure that can be programmed at low voltage and current and which potentially consumes very little chip spaces and can be formed interstitially between elements spaced by a minimum lithographic feature size is formed on a composite substrate such as a silicon-on-insulator wafer by etching a contact through an insulator to a support semiconductor layer, preferably in combination with formation of a capacitor-like structure reaching to or into the support layer. The anti-fuse may be programmed either by the selected location of conductor formation and/or damaging a dielectric of the capacitor-like structure. An insulating collar is used to surround a portion of either the conductor or the capacitor-like structure to confine damage to the desired location. Heating effects voltage and noise due to programming currents are effectively isolated to the bulk silicon layer, permitting programming during normal operation of the device. Thus the potential for self-repair without interruption of operation is realized.

摘要： A word line for a row of memory elements of a dynamic random access memory. A first transistor is connected to a source of negative potential and to the word line for switching the word line to a source of negative potential in response to a decoder signal. A diode is additionally connected to the word line and to a selector signal. A second transistor applies a positive potential to the word line in response to a decoder signal. The word line is charged to a positive potential. The word line is reset to a substantially negative potential in two stages. In the first stage, conduction is through the diode to a ground connection which dissipates a majority of the charge of the word line. The remaining charge is dissipated during a second stage when the first transistor discharges the word line remaining charge through a source of negative potential.
