  • Publication number: 20230352584
    Abstract: Technologies for a transistor with a ferroelectric gate dielectric are disclosed. In the illustrative embodiment, a transistor has a ferroelectric gate dielectric that is lattice matched to the channel of the transistor. In one embodiment, the ferroelectric polarization changes when voltage is applied and removed from a gate electrode, facilitating switching of the transistor at a lower applied voltage. In another embodiment, the ferroelectric polarization of a gate dielectric of a transistor changes when the voltage is past a positive threshold value or a negative threshold value. Such a transistor can be used as a one transistor memory cell.

  • Publication number: 20230317783
    Abstract: Embodiments described herein may be related to forming nano ribbon transistors using layered 2D semiconductor channels. The layered 2D semiconductor channels may be created by forming a scaffold structure that has a first edge that extends from a silicon-based substrate, and a second edge opposite the first edge that is distal to the silicon based substrate. Alternating layers of 2D semiconductor material and a 3D semiconductor material may then be built on the second edge of the scaffold structure. In embodiments, the 3D semiconductor material may then be removed and a gate material deposited around at least a portion of the layers of 2D semiconductor material.

  • Patent number: 11734174
    Abstract: Described is an low overhead method and apparatus to reconfigure a pair of buffered interconnect links to operate in one of these three modes—first mode (e.g., bandwidth mode), second mode (e.g., latency mode), and third mode (e.g., energy mode). In bandwidth mode, each link in the pair buffered interconnect links carries a unique signal from source to destination. In latency mode, both links in the pair carry the same signal from source to destination, where one link in the pair is “primary” and other is called the “assist”. Temporal alignment of transitions in this pair of buffered interconnects reduces the effective capacitance of primary, thereby reducing delay or latency. In energy mode, one link in the pair, the primary, alone carries a signal, while the other link in the pair is idle. An idle neighbor on one side reduces energy consumption of the primary.

  • Publication number: 20230253444
    Abstract: Described herein are capacitor devices formed using perovskite insulators. In one example, a perovskite templating material is formed over an electrode, and a perovskite insulator layer is grown over the templating material. The templating material improves the crystal structure and electrical properties in the perovskite insulator layer. One or both electrodes may be ruthenium. In another example, a perovskite insulator layer is formed between two layers of indium tin oxide (ITO), with the ITO layers forming the capacitor electrodes.

  • Publication number: 20230200079
    Abstract: A first type of ferroelectric capacitor comprises electrodes and an insulating layer comprising ferroelectric oxides. In some embodiments, the electrodes and the insulating layer comprise perovskite ferroelectric oxides. A second type of ferroelectric capacitor comprises a ferroelectric insulating layer comprising certain monochalcogenides. Both types of ferroelectric capacitors can have a coercive voltage that is less than one volt. Such capacitors are attractive for use in low-voltage non-volatile embedded memories for next-generation semiconductor manufacturing technologies.

  • Publication number: 20230197836
    Abstract: Described herein are integrated circuit devices with conductive regions formed from MX or MAX materials. MAX materials are layered, hexagonal carbides and nitrides that include an early transition metal (M) and an A group element (A). MX materials remove the A group element. MAX and MX materials are highly conductive, and their two-dimensional layer structure allows very thin layers to be formed. MAX or MX materials can be used to form several conductive elements of IC circuits, including contacts, interconnects, or liners or barrier regions for contacts or interconnects.

  • Publication number: 20230180482
    Abstract: Three-dimensional hysteretic memory based on semiconductor nanoribbons is disclosed. An example memory cell may include a nanoribbon-based access transistor and a capacitor coupled to the access transistor, where the capacitor at least partially wraps around the nanoribbon in which the access transistor is formed. One or both of a gate stack of the access transistor and the capacitor insulator may include a hysteretic material/arrangement. Plurality of such memory cells may be provided in a single nanoribbon, and the nanoribbon may be one of a stack of nanoribbons provided above one another over a support structure. Incorporating hysteretic memory cells in different layers above a support structure by using stacks of semiconductor nanoribbons may allow significantly increasing density of hysteretic memory cells in a memory array having a given footprint area, or conversely, significantly reducing the footprint area of the memory array with a given density of hysteretic memory cells.
