摘要： An electrical antifuse comprising a field effect transistor includes a gate dielectric having two gate dielectric portions. Upon application of electric field across the gate dielectric, the magnitude of the electrical field is locally enhanced at the boundary between the thick and thin gate dielectric portions due to the geometry, thereby allowing programming of the electrical antifuse at a lower supply voltage between the two electrodes, i.e., the body and the gate electrode of the transistor, across the gate dielectric.

摘要： A method of fabricating a memory device is provided that may begin with forming a layered gate stack atop a semiconductor substrate and patterning a metal electrode layer stopping on the high-k gate dielectric layer of the layered gate stack to provide a first metal gate electrode and a second metal gate electrode on the semiconductor substrate. In a next process sequence, at least one spacer is formed on the first metal gate electrode atop a portion of the high-k gate dielectric layer, wherein a remaining portion of the high-k gate dielectric is exposed. The remaining portion of the high-k gate dielectric layer is etched to provide a first high-k gate dielectric having a portion that extends beyond a sidewall of the first metal gate electrode and a second high-k gate dielectric having an edge that is aligned to a sidewall of the second metal gate electrode.

摘要： A method forms an anti-fuse structure comprises a plurality of parallel conductive fins positioned on a substrate, each of the fins has a first end and a second end. A second electrical conductor is electrically connected to the second end of the fins. An insulator covers the first end of the fins and a first electrical conductor is positioned on the insulator. The first electrical conductor is electrically insulated from the first end of the fins by the insulator. The insulator is formed to a thickness sufficient to break down on the application of a predetermined voltage between the second electrical conductor and the first electrical conductor and thereby form an uninterrupted electrical connection between the second electrical conductor and the first electrical conductor through the fins.
