Abstract:
1. A method of forming a conductive pattern on a substrate, comprising: forming a mold layer having an opening on said substrate; forming a conductive layer on the mold layer and in the opening, the conductive layer having a substantially uniform thickness; forming a buffer layer pattern to fill the opening having the conductive layer, the buffer layer pattern having a cross-linked structure of water-soluble copolymers including a repeating unit of N-vinyl-2-pyrrolidone and a repeating unit of an acrylate; and etching an upper portion of the conductive layer exposed over the buffer layer pattern to form said conductive pattern on the substrate, wherein the water-soluble copolymer has a number average molecular weight of about 7,000 to about 15,000.
