    摘要: A phase shift mask having a first region and a second region in a transverse direction includes a transparent layer, a phase shift pattern disposed in the first region, a transmittance control layer pattern disposed in the second region, and a shading layer pattern disposed on the transmittance control layer pattern. The phase shift pattern has a first pattern including a transparent material and a second pattern including metal. The phase shift mask may prevent haze effects through a cleaning process using an alkaline cleaning solution.

    摘要: In the method of forming fine patterns of a semiconductor integrated circuit, a mask layer is formed over a semiconductor structure having a first region and a second region. A portion of the mask layer over the first region is removed to expose the semiconductor structure, and sacrificial layer patterns are formed over the exposed semiconductor structure. Then, spacers are formed on sidewalls of the sacrificial layer patterns and the mask layer, and portions of the spacers are removed to create fine mask patterns. The semiconductor structure is then patterned using the fine mask patterns to create fine patterns.
