Publication number: 20240120415Abstract: 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.Type: ApplicationFiled: October 1, 2022Publication date: April 11, 2024Applicant: Intel CorporationInventors: Scott B.

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.

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. 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.Type: ApplicationFiled: September 30, 2022Publication date: April 4, 2024Applicant: Intel CorporationInventors: Arnab Sen Gupta, Ian Alexander Young, Dmitri Evgenievich Nikonov, Marko Radosavljevic, Matthew V.
