    摘要: A plasma treatment method which is capable of extending the MTF (mean-time-to-failure) of metal interconnects fabricated on a semiconductor wafer substrate, is disclosed. The invention includes providing a trench typically in a dielectric layer on a substrate; depositing a metal in the trench; and exposing the metal to a nitrogen-based plasma. The plasma-treatment step accelerates grain growth and re-orients the grains in the metal to a closely-packed crystal orientation texture which approaches or approximates the crystal orientation texture of copper.

    摘要: A shallow trench isolation (STI) structure for semiconductor devices is formed using a deposited silicon layer formed over a polish stop layer formed over an oxide formed on a substrate. The polish stop layer may be nitride. An opening is formed extending through the deposited silicon layer and the nitride and oxide layers and extending into the substrate. A deposited oxide is formed filling the opening and extending over the top surface of deposited silicon layer. A chemical mechanical polishing operation polishes the deposited silicon layer at a rate faster than the deposited oxide layer to produce an STI with a convex portion extending above the nitride layer. Dishing problems are avoided and the structure may be subsequently planarized.

    摘要: A method for capping over a copper layer. A copper layer is deposited overlying a substrate. The copper surface is treated with hydrogen-containing plasma to remove copper oxides formed thereon, thereby suppressing copper hillock formation. The treated copper surface is treated again with nitrogen-containing plasma to improve adhesion of the copper surface. A capping layer is formed on the copper layer.

    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.
