Abstract: A capacitor device, such as a metal insulator metal (MIM) capacitor includes a seed layer including tantalum, a first electrode on the seed layer, where the first electrode includes at least one of ruthenium or iridium and an insulator layer on the seed layer, where the insulator layer includes oxygen and one or more of Sr, Ba or Ti. In an exemplary embodiment, the insulator layer is a crystallized layer having a substantially smooth surface. A crystallized insulator layer having a substantially smooth surface facilitates low electrical leakage in the MIM capacitor. The capacitor device further includes a second electrode layer on the insulator layer, where the second electrode layer includes a second metal or a second metal alloy.

Abstract: Described is a ferroelectric-based capacitor that improves reliability of a ferroelectric memory by providing tensile stress along a plane (e.g., x-axis) of a ferroelectric or anti-ferroelectric material of the ferroelectric/anti-ferroelectric based capacitor. Tensile stress is provided by a spacer comprising metal, semimetal, or oxide (e.g., metal or oxide of one or more of: Al, Ti, Hf, Si, Ir, or N). The tensile stress provides polar orthorhombic phase to the ferroelectric material and tetragonal phase to the anti-ferroelectric material. As such, memory window and reliability of the ferroelectric/anti-ferroelectric oxide thin film improves.

Abstract: Fabrication methods for integrated circuit (IC) structures and devices with different nanoribbon thicknesses are disclosed. In one example, an IC structure includes a stack of nanoribbons stacked above one another over the support, including a first nanoribbon with a first channel region and a second nanoribbon with a second channel region, where the first channel region has a first thickness and the second channel region has a second thickness, and where the first thickness of the first channel region is different (e.g., greater) than the second thickness of the second channel region.

Abstract: An IC device with one or more transistors may also include one or more vias and jumpers for delivering power to the transistors. For instance, a via may be coupled to a power plane. A jumper may be connected to the via and an electrode of a transistor. With the via and jumper, an electrical connection is built between the power plane and the electrode. The via may be self-aligned. The IC device may include a dielectric structure at a first side of the via. A portion of the jumper may be at a second side of the via. The second side opposes the first side. The dielectric structure and the portion of the jumper may be over another dielectric structure that has a different dielectric material from the dielectric structure. The via may be insulated from another electrode of the transistor, which may be coupled to a ground plane.

Abstract: A transistor includes a first channel layer over a second channel layer, where the first and the second channel layers include a monocrystalline transition metal dichalcogenide (TMD). The transistor structure further includes a source structure coupled to a first end of the first and second channel layers, a drain structure coupled to a second end of the first and second channel layers, a gate structure between the source material and the drain material, and between the first channel layer and the second channel layer. The transistor further includes a spacer laterally between the gate structure and the and the source structure and between the gate structure and the drain structure. A liner is between the spacer and the gate structure. The liner is in contact with the first channel layer and the second channel layer and extends between the gate structure and the respective source structure and the drain structure.

Abstract: Techniques are provided to form an integrated circuit having an airgap spacer between at least a transistor gate structure and an adjacent source or drain contact. In one such example, a FET (field effect transistor) includes a gate structure that extends around a fin or any number of nanowires (or nanoribbons or nanosheets, as the case may be) of semiconductor material. The semiconductor material may extend in a first direction between source and drain regions while the gate structure extends over the semiconductor material in a second direction. Airgaps are provided in the regions between the gate structures and the adjacent source/drain contacts. The airgaps have a low dielectric constant (e.g., around 1.0) to reduce the parasitic capacitance between the conductive structures.
