    Abstract: Devices structures utilizing, and methods of forming, tungsten interconnects in semiconductor fabrication are disclosed. Tungsten deposition is accomplished by a three-step process that does not require a resistive nucleation material to be deposited prior to bulk tungsten deposition. By treating a tungsten nitride material with a hydrogen plasma, thereby reducing the tungsten nitride to tungsten, the necessity of a resistive nucleation layer is eliminated. Other embodiments describe methods of tungsten deposition requiring a thinner resistive nucleation material (<10 angstroms) than currently known.

    Abstract: There is provided a solution to the problem of the poor adhesion in the pad portion while inhibiting the dishing in the pad portion. An SiON film, which covers insulating areas and has an opening above Cu pad areas, is formed, and a barrier metal film is formed in the opening of the SiON film. Such constitution provides the structure, in which the upper portion of the interfaces between the Cu pad areas and the insulating areas are covered by the SiON film.

  • Publication number: 20070278680
    Abstract: A grating structure for channeling and concentrating incident radiation includes a regular pattern of elements each with a metallic shell partially surrounding at least one subcavity. The subcavity is filled with a dielectric or semiconductor. Light of one or more predetermined wavelength ranges can be concentrated in the subcavity(s) and then efficiently channeled through the grooves between adjacent elements. An optoelectronic device includes the structure superposed on a substrate, which can be semiconductive, and the elements of the grating used as electrodes and adapted to allow a potential difference between adjacent (electrode) elements. The optoelectronic devices include photodetectors, e.g., metal-semiconductor-metal, pn, pin, avalanche, LEDs, IR emitting devices, and biological or chemical sensors.

  • Patent number: 7285842
    Abstract: Structures employing siloxane epoxy polymers as diffusion barriers adjacent conductive metal layers are disclosed. The siloxane epoxy polymers exhibit excellent adhesion to conductive metals, such as copper, and provide an increase in the electromigration lifetime of metal lines. In addition, the siloxane epoxy polymers have dielectric constants less then 3, and thus, provide improved performance over conventional diffusion barriers.

  • Patent number: 7265450
    Abstract: An inventive semiconductor device includes: a lower interlayer dielectric film provided on a substrate; a lower interconnect made up of a lower barrier metal layer formed along a wall surface of a lower interconnect groove in the lower interlayer dielectric film, and a copper film; and an upper plug and an upper interconnect. The upper plug passes through a silicon nitride film and comes into contact with the copper film of the lower interconnect. The lower interconnect is provided with a large number of convex portions buried in concave portions of the lower interconnect groove. Thus, voids in the lower interconnect are also gettered by the convex portions. Accordingly, the concentration of voids in the contact area between the lower interconnect and the upper plug is relieved, and an increase in contact resistance is suppressed.
