    摘要: Electroless plating can be utilized to form electrical interconnects associated with semiconductor substrates. For instance, a semiconductor substrate can be formed to have a dummy structure thereover with a surface suitable for electroless plating, and to also have a digit line thereover having about the same height as the dummy structure. A layer can be formed over the dummy structure and digit line, and openings can be formed through the layer to the upper surfaces of the dummy structure and digit line. Subsequently, a conductive material can be electroless plated within the openings to form electrical contacts within the openings. The opening extending to the dummy structure can pass through a capacitor electrode, and accordingly the conductive material formed within such opening can be utilized to form electrical contact to the capacitor electrode.

    摘要: An intermediate semiconductor device that includes a semiconductor substrate and an oxide-based layer over the substrate. The oxide-based layer has an activated catalytic surface on at least one selected area thereof which is adapted for electroless plating. The intermediate may also include high aspect ratio capacitor containers, trenches, vias, and other openings whose surfaces can be made conductive by selectively electrolessly plating a metal or metal alloy thereon.

    摘要: A scheme for filling plugs through chemical mechanical polishing comprises depositing a malleable conductive layer over a dielectric layer having openings formed therein. The malleable conductive layer is deposited such that a liner is formed within the openings, however the openings are not completely filled. A chemical mechanical polishing process using an alumina based slurry at a neutral or slightly basic pH and no oxidizer is used to smear the malleable conductive layer sufficiently to fill the remainder of the openings in the dielectric layer forming filled or substantially filled plugs.

    摘要: The present invention provides approaches for electroless deposition of conductive materials onto the surface of oxide-based materials, including nonconductive metal oxides, in a manner that does not require intervening conductive pastes, nucleation layers, or additional seed or activation layers formed over the surface of the oxide-based layer. According to one embodiment of the present invention, a layer of a titanium-based material is formed over an oxide-based surface. The layer of titanium-based material is subsequently removed from the surface of the oxide-based layer in a manner such that the surface of the oxide-based layer is activated for electroless deposition. A metal or metal alloy is then plated over the oxide-based surface using electroless plating techniques.
