US Patent 7326633 - Anisotropic conductive film including metal filled nanotubes

By blaisemouttet

Anisotropic conducting films are useful for bonding semiconductor pins to a circuit board or as an epoxy in LCD manufacture. However, these films generally contain microparticles which limits the effectiveness as scales are reduced to sub-micron dimensions. This patent from Hon Hai Precision teaches an improved anisotropic conductive film including metal filled nanotubes. Claim 1 reads:

1. An anisotropic conductive film, comprising an insulative adhesive film and a plurality of nano-scaled conductive particles, the nano-scaled conductive particles being dispersed in the insulative adhesive film, the nano-scaled conductive particles comprising nanotubes each containing metal particles and polyaniline therein, the polyaniline having at least one of hydrogen atoms and metal ions in its molecular chain.
