  • Patent number: 8518304
    Abstract: The present invention features additions of nanostructures to interconnect conductor particles to: (1) reduce thermal interface resistance by using thermal interposers that have high thermal conductivity nanostructures at their surfaces; (2) improve the anisotropic conductive adhesive interconnection conductivity with microcircuit contact pads; and (3) allow lower compression forces to be applied during the microcircuit fabrication processes which then results in reduced deflection or circuit damage. When pressure is applied during fabrication to spread and compress anisotropic conductive adhesive and the matrix of interconnect particles and circuit conductors, the nano-structures mesh and compress into a more uniform connection than current technology provides, thereby eliminating voids, moisture and other contaminants, increasing the contact surfaces for better electrical and thermal conduction.
