Abstract
A passivation composition and use of the composition in a method of forming a conductive pattern are provided. The passivation composition includes an oxidizing agent, an inorganic base with a general formula M(OH)and a solvent, wherein M is a metal ion and n is the valence number of the metal ion. The method includes the following steps: (a) forming a polymer conductive layer on a substrate, wherein the polymer conductive layer is consisting of a first area and a second area. The first area is corresponding to a conductive area to be formed; and (b) passivating the second area by using the passivation composition to reduce the conductivity of the second area and form the conductive pattern on the substrate.
