  • Patent number: 7638388
    Abstract: In a method of forming a pattern and a method of manufacturing a capacitor using the same, a conductive layer is formed on a mold layer having an opening. A first buffer layer pattern including a polymer having a repeating unit of anthracene-methyl methacrylate and a repeating unit of alkoxyl-vinyl benzene is formed on the conductive layer in the opening. The first buffer layer pattern is baked to cross-link the polymers and form a second buffer layer pattern that is insoluble in a developing solution. The conductive layer on a top portion of the mold layer is selectively removed by using the second buffer layer pattern as an etching mask. Accordingly, a conductive pattern for a semiconductor device is formed. The method of forming a pattern may simplify manufacturing processes for a capacitor and a semiconductor device, and may improve their efficiencies.
