  • Publication number: 20200388622
    Abstract: A method used in fabrication of integrated circuitry comprises forming metal material outwardly of a substrate. At least a majority (i.e., up to and including 100%) of the metal material contains ruthenium in at least one of elemental-form, metal compound-form, or alloy-form. A masking material is formed outwardly of the ruthenium-containing metal material. The masking material comprises at least one of nine specifically enumerated materials or category of materials. The masking material is used as a mask while etching through an exposed portion of the ruthenium-containing metal material to form a feature of integrated circuitry that comprises the ruthenium-containing metal material.

  • Publication number: 20200295005
    Abstract: Some embodiments include an integrated assembly having a first semiconductor material between two regions of a second semiconductor material. The second semiconductor material is a different composition than the first semiconductor material. Hydrogen is diffused within the first and second semiconductor materials. The conductivity of the second semiconductor material increases in response to the hydrogen diffused therein to thereby create a structure having the second semiconductor material as source/drain regions, and having the first semiconductor material as a channel region between the source/drain regions. A transistor gate is adjacent the channel region and is configured to induce an electric field within the channel region. Some embodiments include methods of forming integrated assemblies.

  • Publication number: 20200161434
    Abstract: Some embodiments include an integrated assembly having a gate material, an insulative material adjacent the gate material, and a semiconductor oxide adjacent the insulative material. The semiconductor oxide has a channel region proximate the gate material and spaced from the gate material by the insulative material. An electric field along the gate material induces carrier flow within the channel region, with the carrier flow being along a first direction. The semiconductor oxide includes a grain boundary having a portion which extends along a second direction that crosses the first direction of the carrier flow. In some embodiments, the semiconductor oxide has a grain boundary which extends along the first direction and which is offset from the insulative material by an intervening portion of the semiconductor oxide. The carrier flow is within the intervening region and substantially parallel to the grain boundary. Some embodiments include methods of forming integrated assemblies.
