Abstract: 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.

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, 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.

Abstract: Transistor structures may include a metal oxide contact buffer between a portion of a channel material and source or drain contact metallization. The contact buffer may improve control of transistor channel length by limiting reaction between contact metallization and the channel material. The channel material may be of a first composition and the contact buffer may be of a second composition.

Abstract: In one embodiment, a transistor device includes a gate material layer on a substrate, a ferroelectric (FE) material layer on the gate material, a semiconductor channel material layer on the FE material layer, a first source/drain material on the FE material layer and adjacent the semiconductor channel material layer, and a second source/drain material on the FE material layer and adjacent the semiconductor channel material layer and on an opposite side of the semiconductor channel material layer from the first source/drain material. A first portion of the FE material layer is directly between the gate material and the first source/drain material, and a second portion of the FE material layer is directly between the gate material and the second source/drain material.

Abstract: Semiconductor structures having a source and/or drain with a refractory metal cap, and methods of forming the same, are described herein. In one example, a semiconductor structure includes a channel, a gate, a source, and a drain. The source and drain contain silicon and germanium, and one or both of the source and drain are capped with a semiconductor cap and a refractory metal cap. The semiconductor cap is on the source and/or drain and contains germanium and boron. The refractory metal cap is on the semiconductor cap and contains a refractory metal.

Abstract: Described herein are integrated circuit devices with metal-oxide semiconductor channels and carbon source and drain (S/D) contacts. S/D contacts conduct current to and from the semiconductor devices, e.g., to the source and drain regions of a transistor. Carbon S/D contacts may be particularly useful with semiconductor devices that use certain channel materials, such as indium gallium zinc oxide.

Abstract: In one embodiment, a resonator device includes a substrate comprising a piezoelectric material and a set of electrodes on the substrate. The electrodes are in parallel and a width of the electrodes is equal to a distance between the electrodes. The resonator device further includes a set of switches, with each switch coupled to a respective electrode. The switches are to connect to opposite terminals of an alternating current (AC) signal source and select between the terminals of the AC signal source based on an input signal.

Abstract: Embodiments herein describe techniques for a thin-film transistor (TFT) above a substrate. The transistor includes a contact electrode having a conductive material above the substrate, an epitaxial layer above the contact electrode, and a channel layer including a channel material above the epitaxial layer and above the contact electrode. The channel layer is in contact at least partially with the epitaxial layer. A conduction band of the channel material and a conduction band of a material of the epitaxial layer are substantially aligned with an energy level of the conductive material of the contact electrode. A bandgap of the material of the epitaxial layer is smaller than a bandgap of the channel material. Furthermore, a gate electrode is above the channel layer, and separated from the channel layer by a gate dielectric layer. Other embodiments may be described and/or claimed.

Abstract: Capacitors with a carbon-based electrode layer in contact with a ferroelectric insulator. The insulator may be a perovskite oxide. Low reactivity of the carbon-based electrode may improve stability of a ferroelectric capacitor. A carbon-based electrode layer may be predominantly carbon and have a low electrical resistivity. A carbon-based electrode layer may be the only layer of an electrode, or it may be a barrier between the insulator and another electrode layer. Both electrodes of a capacitor may include a carbon-based electrode layer, or a carbon-based electrode layer may be included in only one electrode.
