An anisotropic conductive film (10) is used for bonding a semiconductor
component to a circuit board. The anisotropic conductive film includes an
insulative adhesive film (12) and a plurality of nano-scaled conductive
particles (14). The nano-scaled conductive particles are dispersed in the
insulative adhesive film. The nano-scaled conductive particles are a
nanotubes each containing metal particles and polyaniline therein.
Because the sizes of the nano-scaled conductive particle are very small,
more of the nano-scaled conductive particles can be compressed between
two corresponding contacts of the semiconductor component and the circuit
board. The interface area between the two corresponding contacts is
correspondingly enlarged. In addition, the polyaniline both in the
opening and inside of the nanotubes also has a more favorable viscosity.
The bonding effect between a semiconductor component and a circuit board
is improved.
