    摘要: A spin-on cap useful as a post-CMP cap for Cu interconnect structures is provided. The inventive spin-on cap includes a low-k dielectric (on the order of 3.5 or less) and at least one additive. The at least one additive employed in the present invention is capable of binding Cu ions, and is soluble in the spun-on low-k dielectric. The spin-on cap of the present invention may further include a spun-on low-k (on the order of 3.5 or less) reactive-ion etch (RIE) stop layer. Spin-on caps containing a bilayer of low-dielectric plus at least additive and low-k RIE stop layer are preferred. It is noted that the inventive spin-on cap of the present invention does not significantly increase the effective dielectric constant of the interconnect structure and does not add additional cost to the fabrication of the interconnect structure since a single deposition tool, i.e., spin coating tool, is employed. Moreover, because of the presence of the additive in the spin-on cap, Cu migration is substantially minimized.

    摘要: A metal plus low dielectric constant (low-k) interconnect structure is provided for a semiconductor device wherein adjacent regions in a surface separated by a dielectric have dimensions in width and spacing in the sub 250 nanometer range, and in which reduced lateral leakage current between adjacent metal lines, and a lower effective dielectric constant than a conventional structure, is achieved by the positioning of a differentiating or mask member that is applied for the protection of the dielectric in subsequent processing operations, at a position about 2-5 nanometers below a, to be planarized, surface where there will be a lower electric field. The invention is particularly useful in the damascene type device structure in the art wherein adjacent conductors extend from a substrate through an interlevel dielectric material, connections are made in a trench, a diffusion barrier liner is provided in the interlevel dielectric material and masking is employed to protect the dielectric material between conductors during processing operations.

    摘要: A structure includes a metal nitride film of the form MN, where M is selected from the group consisting of Ga, In, AlGa, AlIn, and AlGaIn. The structure has at least one electrically conductive metal region that is formed within and from the metal nitride film by a thermal process driven by absorption of light having a predetermined wavelength. Single films comprised of AlN are also within the scope of this invention, wherein an Al trace or interconnect is formed by laser radiation of wavelength 248 nm so as to contact circuitry that exists under the film. Multilayered stacks of films are also within the scope of the teachings of this invention. In this case each film layer may be separately deposited and then illuminated to selectively form the desired electrical connection(s), which may also connect to conductive feature(s) in an underlying layer, or a plurality of metal nitride layers are stacked bottom to top in order of increasing electronic band gap energy value, and then the conductive features are written into selective ones of the layers by controlling the wavelength of the light to be absorbed in a desired layer. The teachings of this invention can be employed to fabricate fuses and anti-fuses enabling selective circuit customization, test and repair. Also disclosed is a technique for forming electrical resistors in a metal nitride layer by adjusting the electrical resistance of the metallization formed from the metal nitride film layer.
