  • Publication number: 20080179749
    Abstract: Defect density of a polysilicon metal silicide wiring is reduced by employing a block of undoped polysilicon metal silicide in locations in which dopants are not needed in the underlying polysilicon. Furthermore, detection of presence of defects in the polysilicon metal wiring that adversely impacts device performance at high frequency is facilitated by employing a block of undoped polysilicon metal silicide since defects in undoped polysilicon metal silicide is more readily detectable than defects in doped polysilicon metal silicide. Locations wherein undoped polysilicon metal silicide wiring is employed include areas over shallow trench isolation.

  • Patent number: 7397124
    Abstract: A process of metal interconnects and a structure of metal interconnect produced therefrom are provided. An opening is formed in a dielectric layer. A metal layer is formed over the dielectric layer filling the opening. A film layer is formed on the metal layer and the dielectric layer. The film layer is reacted with the metal layer during a thermal process, and a protective layer is formed on the surface of the metal layer. The portion of the film layer not reacted with the metal layer is removed to avoid short between the metal layers. The protective layer can protect the surface of the metal layer from being oxidized and thus the stability and the reliability of the semiconductor device can be effectively promoted.

  • Patent number: 7332811
    Abstract: A method for forming an electrical interconnect overlying a buried contact region of a substrate is characterized by a deposition of a first polycrystalline silicon layer and the patterning and etching of same to form a via. The via is formed in the first polycrystalline silicon layer to expose the substrate and a second polycrystalline silicon layer is formed in the via to contact the substrate. Portions of the second polycrystalline silicon layer overlying the first polycrystalline silicon layer are removed eliminating any horizontal interface between the two polycrystalline silicon layers. The first polycrystalline silicon layer remaining after the etch is then patterned to form an electrical interconnect.

    Abstract: In a display apparatus, a display panel receives a driving signal from a driving chip through a pad and displays an image in response to the driving signal. The driving chip includes a terminal outputting the driving signal. The driving chip is mounted on the display panel using the anisotropic conductive film and electrically connected to the display panel. A lubricant layer is formed on a surface of the anisotropic conductive film to prevent an electrical defect in the connection between the driving chip and the display panel. Thus, the display apparatus may have improved yield.
