Patent ID: 7776407

Claim:
A method for forming a fine wiring, the method comprising: performing the pre-treatment of a surface of a substrate for forming fine wirings on the substrate, wherein the pre-treatment comprises: preparing the substrate to form a fine wiring; and treating the surface of the substrate with a fluorine containing liquid having a boiling point in the range of 0° C. to 70° C. by way of dipping, spraying or printing in order to temporarily lower a surface energy of the substrate from an original surface energy of the substrate until the fluorine containing liquid has a boiling point of 0° C. to 70° C. evaporates; and forming a metal wiring on the surface-treated substrate with ink-jetting of ink compositing containing metal nano particles before the liquid having a boiling point of 0° C. to 70° C. evaporates.
