摘要： An interconnect structure which includes a plating seed layer that has enhanced conductive material, preferably, Cu, diffusion properties is provided that eliminates the need for utilizing separate diffusion and seed layers. Specifically, the present invention provides an oxygen/nitrogen transition region within a plating seed layer for interconnect metal diffusion enhancement. The plating seed layer may include Ru, Ir or alloys thereof, and the interconnect conductive material may include Cu, Al, AlCu, W, Ag, Au and the like. Preferably, the interconnect conductive material is Cu or AlCu. In more specific terms, the present invention provides a single seeding layer which includes an oxygen/nitrogen transition region sandwiched between top and bottom seed regions. The presence of the oxygen/nitrogen transition region within the plating seed layer dramatically enhances the diffusion barrier resistance of the plating seed.

摘要： A sputter-etching method employed to achieve a thinned down noble metal liner layer deposited on the surface or field of an intermediate back end of the line (BEOL) interconnect structure. The noble metal liner layer is substantially thinned down to a point where the effect of the noble metal has no significant effect in the chemical-mechanical polishing (CMP) process. The noble metal liner layer may be completely removed by sputter etching to facilitate effective planarization by chemical-mechanical polishing to take place.

摘要： An interconnect structure and method of fabricating the same is provided. The interconnect structure is a highly reliable copper interconnect structure. The interconnect structure includes a planarized lower dielectric layer and a lower cap layer on the planarized lower dielectric layer. A copper material is formed in a trench of the planarized lower dielectric layer, below the lower cap layer. A lower liner extends into a pattern of the lower cap layer and contacts the copper layer. An upper dielectric layer is on the lower cap layer and a copper layer contacts the lower liner and is formed in a via of at least the lower cap layer. An upper liner is formed over the copper layer, sandwiching the copper layer between the lower liner and the upper liner. An upper copper layer is formed over the upper liner.
