摘要:
In a method of forming a pattern, a mold layer having an opening is formed on a substrate. A conductive layer is formed on the mold layer having the opening, the conductive layer having a substantially uniform thickness. A buffer layer pattern is formed in 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 acrylate. An upper portion of the conductive layer exposed over the buffer layer pattern is etched. Accordingly, a conductive pattern for a semiconductor device is formed on the substrate. The method of forming a pattern may simplify manufacturing processes for a capacitor and a semiconductor device, and may improve their efficiencies.
