    Abstract: 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 dilectric material and masking is employed to protect the dilectric material between conductors during processing operations.

    Abstract: 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.
