Claim Text:
1. A method of forming a conductive pattern on a substrate, comprising 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 and the first area is corresponding to a conductive pattern to be formed; and (b) passivating the second area by using a passivation composition to reduce the conductivity of the second area and form the conductive pattern on the substrate, wherein the passivating process of the step (b) is performed by a soaking method comprising the following steps: (b-1) applying an anti-passivation film on the first area to cover the first area; (b-2) soaking the conductive substrate into the passivation composition to perform the passivation process to reduce the conductivity of the second area; and (b-3) removing the anti-passivation film from the conductive substrate after the passivation process, wherein the passivation composition comprises an oxidizing agent, an inorganic base having a general formula M(OH) wherein based on the total weight of the passivation composition, the amount of the oxidizing agent ranges from about 5 wt % to about 19.92 wt %, and the amount of the inorganic base ranges from about 0.2 wt % to about 20 wt %.
