    摘要: A method for forming a composite barrier layer that also functions as an etch stop in a damascene process is disclosed. A SiC layer is deposited on a substrate in a CVD process chamber followed by deposition of a silicon nitride layer to complete the composite barrier layer. The SiC layer exhibits excellent adhesion to a copper layer in the substrate and is formed by a method that avoids reactive Si+4 species and thereby prevents CuSiX formation. The silicon nitride layer thickness is sufficient to provide superior barrier capability to metal ions but is kept as thin as possible to minimize the dielectric constant of the composite barrier layer. The composite barrier layer provides excellent resistance to copper oxidation during oxygen ashing steps and enables a copper layer to be fabricated with a lower leakage current than when a conventional silicon nitride barrier layer is employed.

    摘要: A method is disclosed for reducing metal diffusion in a semiconductor device. After forming a first metal portion over a substrate, a silicon carbon nitro-oxide (SiCNO) layer is deposited on the first metal portion. A dielectric layer is deposited over the SiCNO layer, and an opening is generated in the SiCNO layer and the dielectric layer for a second metal portion to be connected to the first metal portion, wherein the SiCNO layer reduces the diffusion of the first metal portion into the dielectric layer.

    摘要: Two problems seen in CMP as currently executed are a tendency for slurry particles to remain on the surface and the formation of a final layer of oxide. These problems have been solved by adding to the slurry a quantity of TMAH or TBAH. This has the effect of rendering the surface being polished hydrophobic. In that state a residual layer of oxide will not be left on the surface at the conclusion of CMP. Nor will many slurry abrasive particles remain cling to the freshly polished surface. Those that do are readily removed by a simple rinse or buffing. As an alternative, the CMP process may be performed in three stages—first convention CMP, then polishing in a solution of TMAH or TBAH, and finally a gentle rinse or buffing.
