Patent ID: 7645512

Claim:
An anisotropic conductive adhesive, mechanically and electrically interconnecting at least two components adjacent to the adhesive and disposed along a common compression axis through the adhesive, and electrically isolating the at least two components from at least one third component also adjacent to the adhesive and not being disposed along a common compression axis with respect to the at least two components, to thereby provide anisotropic electrical conduction properties, the at least two components and the at least one third component embodying an electronic circuit, said anisotropic conductive adhesive comprising: (a) an electrically insulating adhesive carrier mechanically interconnecting the at least two components spaced across the compression axis through the adhesive and the at least one third component, and to exclude external moisture after curing; (b) a plurality of fine interconnect particles suspended in said electrically insulating adhesive carrier, each of said fine interconnect particles having an outer surface; and (c) a plurality of electrically and thermally conductive nano-structures, forming a coating on at least a portion of said outer surface of said fine interconnect particles, said coating providing increased thermal conductivity of the anisotrophic conductive adhesive, with respect to a particle without said non-structures, wherein said plurality of fine interconnect particles having a plurality of electrically and thermally conductive nano-structures formed on said outer surface thereof are provided: (i) in sufficient proportion within said electrically insulating carrier such that, after compression and curing of said electrically insulating adhesive carrier, an electrical pathway is selectively formed across a gap along the compression axis between the at least two components through said plurality of fine interconnect particles by a meshing of said plurality of electrically and thermally conductive nano-structures of adjacent particles along the common compression axis, and (ii) in limited proportion such that the at least one third component displaced from the common compression axis of the at least two components is substantially electrically insulated from the at least two components by portions of said electrically insulating adhesive carrier which are not connected by a meshing of said plurality of electrically and thermally conductive nano-structures of adjacent particles.
