  • Publication number: 20220328346
    Abstract: An integrated circuit device includes a dielectric structure within a metal interconnect over a substrate. The dielectric structure includes a cavity. A first dielectric layer provides a roof for the cavity. A second dielectric layer provides a floor for the cavity. A material distinct from the first dielectric layer and the second dielectric layer provides a side edge for the cavity. In a central area of the cavity, the cavity has a constant height. The height may be selected to provide a low parasitic capacitance between features above and below the cavity. The roof of the cavity may be flat. A gate dielectric may be formed over the roof. The dielectric structure is particularly useful for reducing parasitic capacitances when employing back-end-of-line (BEOL) transistors.

  • Publication number: 20220328560
    Abstract: Various embodiments of the present application are directed towards a bipolar selector having independently tunable threshold voltages, as well as a memory cell comprising the bipolar selector and a memory array comprising the memory cell. In some embodiments, the bipolar selector comprises a first unipolar selector and a second unipolar selector. The first and second unipolar selectors are electrically coupled in parallel with opposite orientations and may, for example, be diodes or some other suitable unipolar selectors. By placing the first and second unipolar selectors in parallel with opposite orientations, the first unipolar selector independently defines a first threshold voltage of the bipolar selector and the second unipolar selector independently defines a second threshold voltage of the bipolar selector. As a result, the first and second threshold voltages can be independently tuned by adjusting parameters of the first and second unipolar selectors.
