A conductive layer is formed on the substrate. A buffer layer pattern is formed on the conductive layer formed in the opening. The buffer layer pattern includes a siloxane polymer represented by the following Chemical Formula 1. The conductive layer is selectively removed to form a lower electrode. The mold layer pattern and the buffer layer pattern are removed. A dielectric layer and an upper electrode are formed on the substrate to form a capacitor. The methods may simplify manufacturing processes for a capacitor and a semiconductor device, and may improve their efficiencies.

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.

摘要:
A method of manufacturing a semiconductor device using a photolithography process may include forming an anti-reflective layer and a first photoresist film on a lower surface. The first photoresist film may be exposed to light and a first photoresist pattern having a first opening may be formed by developing the first photoresist film. A plasma treatment can be performed on the first photoresist pattern and a second photoresist film may be formed on the first photoresist pattern, which may be exposed to light. A second photoresist pattern may be formed to have a second opening by developing the second photoresist film. Here, the second opening may be substantially narrower than the first opening.
