  • Patent number: 8486824
    Abstract: A protection layer is coated or otherwise formed over the interconnect structure. The interconnect structure includes a metal line (such as top and bottom metal layers connected by a metal via) and a low-K material. The protection layer includes a vertically aligned dielectric or other material dispersed with carbon nanotubes. The protection layer could include one or multiple layers of carbon nanotubes, and the carbon nanotubes could have any suitable dispersion, alignment, and pattern in each layer of the protection layer. Among other things, the carbon nanotubes help to reduce or prevent damage to the interconnect structure, such as by reducing or preventing the collapse of the low-K material or delamination between the metal line and the low-K material.

  • Publication number: 20120058255
    Abstract: Electrically conductive polymer materials, such as mixtures of poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(styrenesulfonate) (PSS) are combined with functionalized carbon nanotubes to form composites that exhibit increased electrical conductivity. Functionalized or non-functionalized carbon nanotubes combined with the same electrically conductive polymer materials are combined with non-conductive polymers to increase the electrical conductivity of the non-conductive polymer. The functionalized carbon nanotubes are functionalized with carboxyl and/or hydroxyl groups. The resulting materials are useful in methods of forming electrically conductive films and electrically conductive features.
