  • Patent number: 8394715
    Abstract: A method of fabricating a through-silicon via (TSV) structure forming a unique coaxial or triaxial interconnect within the silicon substrate. The TSV structure is provided with two or more independent electrical conductors insulated from another and from the substrate. The electrical conductors can be connected to different voltages or ground, making it possible to operate the TSV structure as a coaxial or triaxial device. Multiple layers using various insulator materials can be used as insulator, wherein the layers are selected based on dielectric properties, fill properties, interfacial adhesion, CTE match, and the like. The TSV structure overcomes defects in the outer insulation layer that may lead to leakage.

  • Patent number: 8389401
    Abstract: When forming contact levels of sophisticated semiconductor devices, a superior bottom to top fill behavior may be accomplished by applying an activation material selectively in the lower part of the contact openings and using a selective deposition technique. Consequently, deposition-related irregularities, such as voids, may be efficiently suppressed even for high aspect ratio contact openings.

    Abstract: A metal interconnect structure includes at least a pair of metal lines, a cavity therebetween, and a dielectric metal-diffusion barrier layer located on at least one portion of walls of the cavity. After formation of a cavity between the pair of metal lines, the dielectric metal-diffusion barrier layer is formed on the exposed surfaces of the cavity. A dielectric material layer is formed above the pair of metal lines to encapsulate the cavity. The dielectric metal-diffusion barrier layer prevents diffusion of metal and impurities from one metal line to another metal line and vice versa, thereby preventing electrical shorts between the pair of metal lines.
