Abstract

See full text

In a conductive film forming method using photo sintering, a conductive film having low electric resistance is easily formed. Disclosed is a conductive film forming method in which a conductive film is formed using a photo sintering, which includes the steps of: forming a liquid film made of a copper particulate dispersion on a substrate, drying the liquid film to form a copper particulate layer, subjecting the copper particulate layer to photo sintering to form a conductive film, attaching a sintering promoter to the conductive film, and further subjecting the conductive film having the sintering promoter attached to photo sintering. The sintering promoter is a compound which removes copper oxide from metallic copper. Thereby, the sintering promoter removes a surface oxide film of copper particulates in the conductive film.
