    Abstract: A template, a method of forming the template and a method of forming a photoresist pattern using a lithographic template is disclosed. In the method, a photoresist film is formed on a substrate. A template for selectively transmitting light is pressed on the photoresist film. The template includes a transparent plate through which light passes, a blocking pattern formed thereon for selectively blocking the light passing through the transparent plate, and a plurality of concave and convex portions for imprinting the photoresist film. The concave and convex portions are formed in accordance with the blocking pattern. The photoresist film is partially exposed to light selectively passing through the template, and the photoresist film that has been exposed to the light is also partially developed to form the photoresist pattern.

    Abstract: 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.
