Abstract:
1. A method for fabricating conductive patterns on a non-conductive substrate comprising the steps of: (i) forming a resist layer on the non-conductive substrate; (ii) forming pattern grooves in the resist layer using a laser beam; (iii) forming a conductive layer comprising a conductive material and a blackening material in the pattern grooves; and (iv) removing the resist layer remained on the non-conductive substrate, wherein the conductive layer is formed by filling and drying a blackening solution containing the blackening material in the pattern grooves, so as to form a first layer, and filling and drying a conductive ink containing the conductive material in the pattern grooves on top of the first layer, so as to form a second layer and then forming a third layer containing the blackening material on top of the second layer, wherein the second layer is surrounded by the first layer and the third layer, and wherein the blackening material is a compound selected from the group consisting of a metal oxide, a metal sulfide, and an organic metal compound and the compound contains one or more metal(s) selected from the group consisting of Cu, Zn, Ni, Co, Ti, Mn, Fe, Cr, Nb, Ru, Cd, Ge, and Sn.
