Publication number: 20250008852Abstract: 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.Type: ApplicationFiled: July 1, 2023Publication date: January 2, 2025Applicant: Intel CorporationInventors: Punyashloka Debashis, Dominique A.

Patent number: 12125893Abstract: Describe is a resonator that uses anti-ferroelectric (AFE) materials in the gate of a transistor as a dielectric. The use of AFE increases the strain/stress generated in the gate of the FinFET. Along with the usual capacitive drive, which is boosted with the increased polarization, additional current drive is also achieved from the piezoelectric response generated to due to AFE material. In some embodiments, the acoustic mode of the resonator is isolated using phononic gratings all around the resonator using the metal line above and vias' to body and dummy fins on the side. As such, a Bragg reflector is formed above or below the AFE based transistor. Increased drive signal from the AFE results in larger output signal and larger bandwidth.Type: GrantFiled: April 3, 2023Date of Patent: October 22, 2024Assignee: Intel CorporationInventors: Tanay Gosavi, Chia-Ching Lin, Raseong Kim, Ashish Verma Penumatcha, Uygar Avci, Ian Young

Patent number: 12113117Abstract: Describe is a resonator that uses ferroelectric (FE) materials in the gate of a transistor as a dielectric. The use of FE increases the strain/stress generated in the gate of the FinFET. Along with the usual capacitive drive, which is boosted with the increased polarization, FE material expands or contacts depending on the applied electric field on the gate of the transistor. As such, acoustic waves are generated by switching polarization of the FE materials. In some embodiments, the acoustic mode of the resonator is isolated using phononic gratings all around the resonator using the metal line above and vias' to body and dummy fins on the side. As such, a Bragg reflector is formed above the FE based transistor.Type: GrantFiled: April 3, 2023Date of Patent: October 8, 2024Assignee: Intel CorporationInventors: Tanay Gosavi, Chia-ching Lin, Raseong Kim, Ashish Verma Penumatcha, Uygar Avci, Ian Young

Publication number: 20240113220Abstract: Technologies for a transistor with a thin-film ferroelectric gate dielectric are disclosed. In the illustrative embodiment, a transistor has a thin layer of scandium aluminum nitride (ScxAl1-xN) ferroelectric gate dielectric. The channel of the transistor may be, e.g., gallium nitride or molybdenum disulfide.

Publication number: 20240113212Abstract: 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, such as undoped semiconductor 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 preferentially etched away, leaving the doped semiconductor layers as fins for a ribbon FET. In another embodiment, an interlayer can be deposited on top of a semiconductor layer, and a ferroelectric layer can be deposited on the interlayer. The interlayer can bridge a gap in lattice parameters between the semiconductor layer and the ferroelectric layer.Type: ApplicationFiled: September 29, 2022Publication date: April 4, 2024Applicant: Intel CorporationInventors: Ian Alexander Young, Dmitri Evgenievich Nikonov, Marko Radosavljevic, Matthew V.
