  • Publication number: 20230197860
    Abstract: A metal chalcogenide material layer of lower quality provides a transition between a metal chalcogenide material layer of higher quality and a gate insulator material that separates the metal chalcogenide material layers from a gate electrode of a metal-oxide semiconductor field effect transistor (MOSFET) structure. Gate insulator material may be more readily initiated and/or or precisely controlled to a particular thickness when formed on lower quality metal chalcogenide material. Accordingly, such a material stack may be integrated into a variety of transistor structures, including multi-gate, multi-channel nanowire or nanosheet transistor structures.

  • Patent number: 11171145
    Abstract: Embodiments herein describe techniques for an integrated circuit (IC). The IC may include a capacitor. The capacitor may include a first electrode, a second electrode, and a paraelectric layer between the first electrode and the second electrode. A first interface with a first work function exists between the paraelectric layer and the first electrode. A second interface with a second work function exists between the paraelectric layer and the second electrode. The paraelectric layer may include a ferroelectric material or an anti-ferroelectric material. A built-in electric field associated with the first work function and the second work function may exist between the first electrode and the second electrode. The built-in electric field may be at a voltage value where the capacitor may operate at a center of a memory window of a polarization-voltage hysteresis loop of the capacitor. Other embodiments may be described and/or claimed.
