METHOD FOR FORMING WIRING AND ELECTRODE USING METAL NANO PASTE

摘要

Disclosed herein is a method for forming a metal wiring and an electrode using a metal nano paste, including a sintering process, wherein the sintering includes: placing a substrate on which a metal nano paste is printed in a furnace and raising a temperature of the furnace to 220 to 240� C. under a nitrogen atmosphere; heating the substrate under a mixed atmosphere of carboxylic acid and air while the temperature of the furnace is maintained at the temperature range; dropping the temperature of the furnace to 100 to 150� C. under the mixed atmosphere of carboxylic acid and air; and dropping the temperature of the furnace to room temperature under a nitrogen atmosphere. According to the present invention, a metal film having high density and a minimized amount of residual metal particles can be formed despite a low-temperature sintering process, like a case where a high-temperature sintering process is employed.
