  • Combination, Method, and Composition for Chemical Mechanical Planarization of A Tungsten-Containing Substrate
    Publication number: 20100159698
    Abstract: A combination, composition and associated method for chemical mechanical planarization of a tungsten-containing substrate are described herein which afford tunability of tungsten/dielectric selectivity and low selectivity for tungsten removal in relation to dielectric material. Removal rates for both tungsten and dielectric are high and stability of the slurry (e.g., with respect to pH drift over time) is high.

  • Method for Chemical Mechanical Planarization of A Metal-containing Substrate
    Publication number: 20090061630
    Abstract: A method using an associated composition for chemical mechanical planarization of a metal-containing substrate (e.g., a copper substrate) is described. This method affords low dishing and local erosion levels on the metal during CMP processing of the metal-containing substrate.

  • Method and slurry for reducing corrosion on tungsten during chemical mechanical polishing
    Publication number: 20080149591
    Abstract: A composition and associated method for the chemical mechanical planarization (CMP) of tungsten-containing substrates on semiconductor wafers are described. The composition contains an anionic fluorosurfactant, a per-type oxidizer (e.g., hydrogen peroxide), and iron. The composition and associated method are effective in affording greatly reduced levels of tungsten etching during tungsten CMP. In some embodiments, certain aspartic acid compounds are also present in the composition and are effective in affording even lower levels of tungsten etching during tungsten CMP.

  • System and method for displaying numbered descriptions
    Publication number: 20080120549
    Abstract: According to a method of the invention, a user can simultaneously display the text and drawings of a document containing a numbered description such as a patent. A computer-implemented system finds a reference number selected by the user/reader in the drawings and displays it in the graphic display, so that the user does not have to hunt for it.
