Patent ID: 8518304

Claim:
A module, comprising: an anisotropic conductive composition, comprising: a electrically insulating carrier composition; a plurality of electrically and thermally conductive interconnect particles suspended in the electrically insulating carrier composition, each having an outer surface, wherein said conductive interconnect particles comprise at least one particle selected from the group consisting of ovoid, disk-like, and tubular particles; and a plurality of electrically conducting elongated nanostructures affixed to and selectively extending away from the outer surface along the elongated axis, wherein the plurality of conductive interconnect particles are provided within a range of concentration sufficient to provide a substantially anisotropic electrical conduction pattern aligned with the compression axis and a high probability of interacting with each other, under compression of a film of the anisotropic conductive composition, and wherein the conducting elongated nanostructures on a respective conductive interconnect particle are adapted to engage and interlock with the conducting elongated nanostructures on another respective conductive interconnect particle when mutually compressed, to form an efficient thermal and electrical conduction path; at least two pairs of opposed contact surfaces, having an intracontact gap between the contact surfaces of a respective pair and an intercontact gap between respective pairs, having a compressed continuous film of the anisotropic conductive composition disposed between the at least two pairs of opposed contact surfaces; and a plurality of electrically isolated conductive paths formed across the intracontact gaps each respective path comprising engaged and interlocked conducting elongated nanostructures, which are mutually isolated by a selectively occurring electrically isolating space in the intercontact gap in which interlocked conducting elongated nanostructures bridging the intercontact gap are substantially absent.
