    摘要: Integrated circuit structures having plugged metal gates, and methods of fabricating integrated circuit structures having plugged metal gates, are described. For example, an integrated circuit structure includes a fin (204) having a portion protruding above a shallow trench isolation (STI) structure (206). A gate dielectric material layer (208) is over the protruding portion of the fin and over the STI structure. A conductive gate layer is over the gate dielectric material layer. A conductive gate fill material is over the conductive gate layer. A dielectric gate plug (212) is laterally spaced apart from the fin, the dielectric gate plug on the STI structure. The gate dielectric material layer and the conductive gate layer are along a side of the dielectric gate plug, and the gate dielectric material layer is in direct contact with an entirety of the side of the dielectric gate plug.

    摘要: Contact over active gate structure with metal oxide layers are described 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. A portion of one of the plurality of trench contact structures has a metal oxide layer 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 the metal oxide layer.
