  • Patent number: 11482528
    Abstract: The memory bit-cell formed using the ferroelectric capacitor results in a taller and narrower bit-cell compared to traditional memory bit-cells. As such, more bit-cells can be packed in a die resulting in a higher density memory that can operate at lower voltages than traditional memories while providing the much sought after non-volatility behavior. The pillar capacitor includes a plug that assists in fabricating a narrow pillar.

  • Patent number: 11476353
    Abstract: The invention relates to heterostructures including a layer of a two-dimensional material placed on a multiferroic layer. An ordered array of differing polarization domains in the multiferroic layer produces corresponding domains having differing properties in the two-dimensional material. When the multiferroic layer is ferroelectric, the ferroelectric polarization domains in the layer produce local electric fields that penetrate the two-dimensional material. The local electric fields modulate the charge carriers and carrier density on a nanometer length scale, resulting in the formation of lateral p-n or p-i-n junctions, and variations thereof appropriate for device functions. Methods for producing the heterostructures are provided. Devices incorporating the heterostructures are also provided.

  • Patent number: 11444086
    Abstract: The present invention relates to a capacitor and its formation method and to a DRAM cell. In various embodiments, a substrate is provided such that an electrical contact portion is formed thereon. A dielectric layer is formed on a surface of the substrate, including alternately stacked supporting layers and sacrificial layers. At least two capacitor holes penetrating the sacrificial layers and the supporting layers can formed to expose the same electrical contact portion. A lower electrode layer covering the inner surface of the capacitor holes can be formed. The lower electrode layer is connected to the electrical contact portion.
