  • Publication number: 20070232069
    Abstract: A CMP apparatus therefor is provided. First, a substrate including a semiconductor structure, a liner layer over the semiconductor structure and a metal layer over the liner layer is provided. Next, a metal polishing step is performed to polish the metal layer until a portion of the liner layer is exposed. Next, a buffing step is performed to remove any contaminants from the surface of the metal layer. Thereafter, a liner CMP step is performed to polish the liner layer.

  • Publication number: 20070082490
    Abstract: An apparatus of chemical mechanical polishing has a polishing machine, a first thickness metrology and a second thickness metrology. The first thickness metrology is connected with the polishing machine, and the second thickness metrology is connected with the polishing machine. Since the thickness of the first material layer and the second material layer after polishing process can be separately measured by the first thickness metrology and the second thickness metrology in-situ, the difference of film thickness between wafers can be reduced.

  • Publication number: 20050159083
    Abstract: A semiconductor wafer has a top surface and an edge bevel surface, and a first material layer and a second material layer are respectively formed on the top surface and the edge bevel surface. A surface chemical mechanical polishing (surface CMP) process is performed to polish and remove portions of the first material layer down to a first thickness, and a rim CMP process is performed to completely remove the second material layer on the edge bevel surface down to the edge bevel surface thereafter to achieve a smooth surface of the edge bevel surface. Finally, a chemical cleaning process is performed to clean the edge bevel surface and the top surface, and the semiconductor wafer is dried thereafter.

  • Patent number: 6319826
    Abstract: A method of forming a barrier layer is described. A dielectric layer is formed on a substrate. The dielectric layer comprises an opening exposing a portion of the substrate. A metallic layer, which is conformal to the opening, is formed on the dielectric layer. A first metallic nitride layer, which is conformal to the opening, is formed on the first metallic layer by chemical vapor deposition. The second metallic nitride layer, which is conformal to the opening, is formed on the first metallic nitride layer.
