COMPOSITE SILVER NANOPARTICLES, COMPOSITE SILVER NANOPASTE, PROCESS FOR PRODUCING THE SAME, MANUFACTURING APPARATUS, JOINING METHOD AND PATTERN FORMING METHOD

摘要

Established a low-temperature production method of composite silver nanoparticles, an alcohol molecule derivative having 1 to 12 carbon atoms, an alcohol molecule residue around silver nuclei having an average particle size in the range of 1 to 20 nm comprising aggregates of silver atoms Composite silver nanoparticle formed with an organic coating layer composed of at least one group or alcohol molecule, composite silver nanopaste containing at least the composite silver nanoparticle and containing a solvent and / or a viscosity-imparting agent, its production method, and production apparatus A bonding method and a pattern forming method are provided. In the method of producing composite silver nanoparticles, silver salt fine particles are mixed in an excess alcohol solvent to prepare an excess alcohol solution and reacted at a predetermined temperature in a reaction chamber for a predetermined time. Silver nuclei are formed from the silver salt, and the alcohol-derived organic coating layer is formed around the silver nuclei.
