Abstract: Contact over active gate structures with metal oxide cap structures are described. In an example, an integrated circuit structure includes a plurality of gate structures above substrate, each of the gate structures including a gate insulating layer thereon. A plurality of conductive trench contact structures is alternating with the plurality of gate structures, each of the conductive trench contact structures including a metal oxide cap structure thereon. An interlayer dielectric material is over the plurality of gate structures and over the plurality of conductive trench contact structures. An opening is in the interlayer dielectric material and in a gate insulating layer of a corresponding one of the plurality of gate structures. A conductive via is in the opening, the conductive via in direct contact with the corresponding one of the plurality of gate structures, and the conductive via on a portion of one or more of the metal oxide cap structures.

Abstract: A memory device includes a first electrode including a spin-orbit material, a magnetic junction on a portion of the first electrode and a first structure including a dielectric on a portion of the first electrode. The first structure has a first sidewall and a second sidewall opposite to the first sidewall. The memory device further includes a second structure on a portion of the first electrode, where the second structure has a sidewall adjacent to the second sidewall of the first structure. The memory device further includes a first conductive interconnect above and coupled with each of the magnetic junction and the second structure and a second conductive interconnect below and coupled with the first electrode, where the second conductive interconnect is laterally distant from the magnetic junction and the second structure.

Abstract: An integrated circuit structure includes a first material block comprising a first block insulator layer and a first multilayer stack on the first block insulator layer, the first multilayer stack comprising interleaved pillar electrodes and insulator layers. A second material block is stacked on the first material block and comprises a second block insulator layer, and a second multilayer stack on the second block insulator layer, the second multilayer stack comprising interleaved pillar electrodes and insulator layers. At least one pillar extends through the first material block and the second material block, wherein the at least one pillar has a top width at a top of the first and second material blocks that is greater than a bottom width at a bottom of the first and second material blocks.
