PRODUCTION OF METALLIC THIN FILM

Abstract:

PROBLEM TO BE SOLVED: To make it possible to produce ultrathin films of metals under an atmosphere pressure by dropping a solution containing micelle type particulates covering metallic particulates in a micelle form by adsorption of organic material molecular chains on the surfaces of the metallic particulates onto a substrate and dissociating the molecular chains after drying.
SOLUTION: While Cr, Zn, Te, Al, etc., are usable as the metallic particulates, multiple twin particles 2 of Au, Ag, Ni, Pd, Pt, Fe, Co, In, etc., are particularly used. The grain size thereof is preferably 1 to 200 nm. The molecular chains 3 of the organic material are preferably mercaptoacetic acid, beta-mercapltopropionic acid, alkanethiol, such as dodecanthiol, etc., and an alkyl group of 2-28C is more preferable. The solution of the micelle type metallic particulates 1 is applied on the substrate under the atmosphere pressure and after the solution is removed by drying, the organic molecules bonded to the micelle type metallic particulates 1 are subjected to heating, irradiation with UV rays, chemical treatment, etc., by which the metallic thin films having an arbitrary thickness are obtained.
