    Abstract: Thermal interface compositions contain both non-electrically conductive micron-sized fillers and electrically conductive nanoparticles blended with a polymer matrix. Such compositions increase the bulk thermal conductivity of the polymer composites as well as decrease thermal interfacial resistances that exist between thermal interface materials and the corresponding mating surfaces. Such compositions are electrically non-conductive. Formulations containing nanoparticles also show less phase separation of micron-sized particles than formulations without nanoparticles.

    Abstract: A no-flow underfill composition comprising an epoxy resin in combination with epoxy hardener and optional reagents and a filler of a functionalized colloidal silica having a particle size ranging from about 1 nm to about 250 nm. The colloidal silica is functionalized with at least one organoalkoxysilane functionalization agent and subsequently functionalized with at least one capping agent. The epoxy hardener includes anhydride curing agents. The optional reagents include cure catalyst and hydroxyl-containing monomer. The adhesion promoters, flame retardants and defoaming agents may also be added to the composition. Further embodiments of the present disclosure include packaged solid state devices comprising the underfill compositions.
