There are provided a method of forming a fine pattern employing self-aligned double patterning. The method includes providing a substrate. First mask patterns are formed on the substrate. A reactive layer is formed on the substrate having the first mask patterns. The reactive layer adjacent to the first mask patterns is reacted using a chemical attachment process, thereby forming sacrificial layers along outer walls of the first mask patterns. The reactive layer that is not reacted is removed to expose the sacrificial layers. Second mask patterns are formed between the sacrificial layers adjacent to sidewalls of the first mask patterns facing each other. The sacrificial layers are removed to expose the first and second mask patterns and the substrate exposed between the first and second mask patterns. The substrate is etched using the first and second mask patterns as an etching mask.

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.

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.

摘要:
Methods of forming a photoresist pattern include forming a first photoresist pattern on a substrate and treating the first photoresist pattern with plasma that modifies etching characteristics of the first photoresist pattern. This modification may include making the first photoresist pattern more susceptible to removal during subsequent processing. The plasma-treated first photoresist pattern is covered with a second photoresist layer, which is patterned into a second photoresist pattern that contacts sidewalls of the plasma-treated first photoresist pattern. The plasma-treated first photoresist pattern is selectively removed from the substrate to reveal the remaining second photoresist pattern. The second photoresist pattern is used as an etching mask during the selective etching of a portion of the substrate (e.g., target layer). The use of the second photoresist pattern as an etching mask may yield narrower linewidths in the etched portion of the substrate than are achievable using the first photoresist pattern alone.
