AQUEOUS DISPERSION FOR FORMING LOW-DIELECTRIC CONSTANT INSULATION FILM, THE RESULTANT LOW-DIELECTRIC CONSTANT INSULATION FILM, AND ELECTRONIC COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide an aqueous dispersion for forming a low dielectric constant insulator film capable of forming organic insulation film by electrodeposition, to provide the low-dielectric constant insulation film obtained from the above aqueous dispersion, and to provide electronic components each having the above low-dielectric constant insulation film. SOLUTION: This aqueous dispersion for forming a low-dielectric constant insulation film is such that film-nonforming microparticles <=1μm in average size and <=3 in dielectric constant and organic particles consisting of a polymerizable compound and/or a polymer are dispersed in an aqueous medium, and is characterized by being capable of forming insulation film by electrodeposition; wherein the film-nonforming microparticles are preferably fluorine-containing microparticles and/or crosslinked organic microparticles, and the organic particles preferably have electric charge on the surface and consist of a polyimide-based resin. The 2nd objective low-dielectric constant insulation film to be formed the above aqueous dispersion by electrodeposition is characterized by being <=3 in dielectric constant. The other objective electronic components are characterized by being provided respectively with the above low- dielectric constant insulation films.
