    摘要: A method of forming a self-aligned logic cell. A nanotube layer is formed over the bottom electrode. A clamp layer is formed over the nanotube layer. The clamp layer covers the nanotube layer, thereby protecting the nanotube layer. A dielectric layer is formed over the clamp layer. The dielectric layer is etched. The clamp layer provides an etch stop and protects the nanotube layer. The clamp layer is etched with an isotropic etchant that etches the clamp layer underneath the dielectric layer, creating an overlap of the dielectric layer, and causing a self-alignment between the clamp layer and the dielectric layer. A spacer layer is formed over the nanotube layer. The spacer layer is etched except for a ring portion around the edge of the dielectric layer. The nanotube layer is etched except for portions that are underlying at least one of the clamp layer, the dielectric layer, and the spacer layer, thereby causing a self-alignment between the clamp layer, the overlap to the dielectric layer, the spacer layer, and the nanotube layer.

    摘要: An integrated barrier and seed layer that is useful for creating conductive pathways in semiconductor devices. The barrier portion of the integrated layer prevents diffusion of the conductive material into the underlying dielectric substrate while the seed portion provides an appropriate foundation upon which to deposit the conductive material. The barrier portion of the integrated layer is formed of a metal nitride, while the seed portion is formed of ruthenium or a ruthenium alloy. The metal nitride forms an effective barrier layer while the ruthenium or ruthenium alloy forms an effective seed layer for a metal such as copper. In some embodiments, the integrated layer is formed in a way so that its composition changes gradually from one region to the next.
