Abstract: A two-terminal ferroelectric perovskite diode comprises a region of ferroelectric perovskite material positioned adjacent to a region of n-type doped perovskite semiconductor material. Asserting a positive voltage across the diode can cause the polarization of the ferroelectric perovskite material to be set in a first direction that causes the diode to be placed in a low resistance state due to the formation of an accumulation region in the perovskite semiconductor material at the ferroelectric perovskite-perovskite semiconductor boundary. Asserting a negative voltage across the diode can cause the polarization of the ferroelectric perovskite material to be set in a second direction that causes the diode to be placed in a high resistance state due to the formation of a depletion region in the perovskite semiconductor material at the ferroelectric perovskite-perovskite semiconductor material. These non-volatile low and high resistance states enable the diode to be used as a non-volatile memory element.

Abstract: An integrated circuit includes: a gate dielectric; a first layer adjacent to the gate dielectric; a second layer adjacent to the first layer, the second layer comprising an amorphous material; a third layer adjacent to the second layer, the third layer comprising a crystalline material; and a source or drain at least partially adjacent to the third layer. In some cases, the crystalline material of the third layer is a first crystalline material, and the first layer comprises a second crystalline material, which may be the same as or different from the first crystalline material. In some cases, the gate dielectric includes a high-K dielectric material. In some cases, the gate dielectric, the first layer, the second layer, the third layer, and the source or drain are part of a back-gate transistor structure (e.g., back-gate TFT), which may be part of a memory structure (e.g., located within an interconnect structure).

Abstract: Technologies for a field effect transistor (FET) with a ferroelectric gate dielectric are disclosed. In an illustrative embodiment, a perovskite stack is grown on a buffer layer as part of manufacturing a transistor. The perovskite stack includes one or more doped semiconductor layers alternating with other lattice-matched layers. Growing the doped semiconductor layers on lattice-matched layers can improve the quality of the doped semiconductor layers. The lattice-matched layers can be etched away, leaving the doped semiconductor layers as fins for a ribbon FET. A ferroelectric layer can be conformally grown on the fins, creating a high-quality ferroelectric layer above and below the fins. A gate can then be grown on the ferroelectric layer.

Abstract: A memory structure includes a spacer between a first side of a wordline conductor and a bitline conductor. A semiconductor material has horizontal portions extending from the bitline conductor along a top and bottom of the wordline conductor and has a contact portion extending along a second side of the wordline conductor between and connecting the horizontal portions. A high-κ dielectric is between the semiconductor material and the wordline conductor. A capacitor has a first conductor, a second conductor, and an insulator between the first and second conductors, where the first conductor contacts the contact portion of the semiconductor material along the first side of the wordline conductor, and the second conductor connects to a ground terminal.
