Abstract: A method for interconnecting components of an electronic system includes depositing a sintering solution onto a first component to form an interconnection layer, the sintering solution comprising a solvent, metal nanoparticles dispersed in the solvent, and a stabilizing agent adsorbed onto the nanoparticles. More than 95.0%, preferably more than 99.0% of the mass of the nanoparticles include a metal selected from silver, gold, copper and alloys thereof and have a polyhedral shape with an aspect ratio greater than 0.8. The method also includes eliminating, at least partially, the solvent from the layer to form an ordered agglomerate in which the nanoparticles are regularly disposed in three axes, the stabilizing agent binding them together and maintaining at least a portion of the nanoparticles at a distance from each other, debinding and sintering the layer, and depositing a second component in contact with the layer before or during debinding or sintering.

Abstract: Method for interconnecting components of an electronic system comprising the steps of: a) depositing a sintering solution onto a first component in order to form an interconnection layer, the sintering solution comprising a solvent, metal nanoparticles dispersed in the solvent, and a stabilizing agent adsorbed onto the metal nanoparticles, more than 95.0%, preferably more than 99.0% of the mass of the metal nanoparticles comprising a metal selected from silver, gold, copper and alloys thereof and having a polyhedral shape with an aspect ratio of more than 0.

Abstract: The invention relates to a composite material constituted by a microporous or mesoporous matrix and nanoparticles of metal or of metal oxide. The material being wherein the material of the matrix is either disordered, or ordered and optionally oriented, and wherein the nanoparticles are i) monodisperse in size when said matrix material is ordered and optionally oriented; ii) either monodisperse in size or of size identical to the size of the pores of the matrix material when said matrix material is disordered. The method of preparing the material consists in impregnating a microporous or mesoporous solid material with a solution of nanoparticle precursors, then in reducing the precursors within said material forming the matrix. Impregnation is performed under saturated vapor pressure and under reflux of the precursor solution, and reduction is performed radiolytically.
