    摘要: A new method of depositing a copper layer, using disproportionation of Cu(I) ions from a solution stabilized by a polar organic solvent, for single and dual damascene interconnects in the manufacture of an integrated circuit device has been achieved. A dielectric layer, which may comprise a stack of dielectric material, is provided overlying a semiconductor substrate. The dielectric layer is patterned to form vias and trenches for planned dual damascene interconnects. A barrier layer is deposited overlying the dielectric layer to line the vias and trenches. A simple Cu(I) ion solution, stabilized by a polar organic solvent, is coated overlying said barrier layer. Water is added to the stabilized simple Cu(I) ion solution to cause disproportionation of the simple Cu(I) ion from the Cu(I) ion solution. A copper layer is deposited overlying the barrier layer. The copper layer may comprise a thin seed layer for use in subsequent electroplating or electroless plating of copper or may comprise a thick copper layer to fill the vias and trenches. The integrated circuit is completed.

    摘要: A method and structure for forming a damascene structure with reduced capacitance by forming one or more of: the passivation layer, the etch stop layer, and the cap layer using a low dielectric constant material comprising carbon nitride, boron nitride, or boron carbon nitride. The method begins by providing a semiconductor structure having a first conductive layer thereover. A passivation layer is formed on the first conductive layer. A first dielectric layer is formed over the passivation layer, and an etch stop layer is formed over the first dielectric layer. A second dielectric layer is formed over the etch stop layer, and an optional cap layer can be formed over the second dielectric layer. The cap layer, the second dielectric layer, the etch stop layer, and the first dielectric layer are patterned to form a via opening stopping on said passivation layer and a trench opening stopping on the first conductive layer. A carbon nitride passivation layer, etch stop layer, or cap layer can be formed by magnetron sputtering from a graphite target in a nitrogen atmosphere. A boron nitride passivation layer, etch stop layer, or cap layer can be formed by PECVD using B.sub.2 H.sub.6, ammonia, and nitrogen. A boron carbon nitride passivatation layer, etch stop layer, or cap layer can be formed by magnetron sputtering from a graphite target in a nitrogen and B.sub.2 H.sub.6 atmosphere.

    摘要: A method for forming upon a reflective layer, such as a reflective conducting layer, within an integrated circuit an Anti-Reflective Coating (ARC) which simultaneously possesses adhesion promotion characteristics for an organic layer to be formed upon the reflective layer. There is first formed upon a semiconductor wafer a reflective integrated circuit layer which may be a hydrophilic reflective integrated circuit layer or a hydrophobic integrated circuit layer. The semiconductor wafer is then immersed into and withdrawn from a Langmuir trough having formed therein a Langmuir-Blodgett (LB) monolayer film of a dye surfactant molecule ordered upon a surface of water. Upon withdrawing the wafer from the Langmuir trough, there is formed upon the reflective integrated circuit layer an ordered LB film of the dye surfactant molecule. The chromophore groups within the dye surfactant molecule and ordered LB film provide ARC characteristics to the reflective layer.

    摘要: Interconnects for integrated circuits, such as damascene structures are formed using a hard mask. The hard mask is formed from, for example, high-k dielectric material such as hafnium oxide or other materials having high etch selectivity to the interconnect dielectric material. This enables a thin mask to etch vias and trenches in the interconnect dielectric layer, avoiding the problems associated with the use of thick mask layers, such as contact hole striations and small depth of focus, which can result in shorts or opens.
