摘要:
A method of forming patterns may use an organic reflection-preventing film including a polymer having an acid-liable group. A photoresist film is formed on the organic reflection-preventing film. A first area selected from the photoresist film is exposed to generate an acid in the first area. Hydrophilicity of a first surface of the organic reflection-preventing film facing the first area of the photoresist film may be increased. The photoresist film including the exposed first area is developed to remove a non-exposed area of the photoresist film. The organic reflection-preventing film and a target layer are anisotropically etched by using the first area of the photoresist film as an etch mask.

A method of forming fine patterns of a semiconductor device includes forming a plurality of first mask patterns on a substrate such that the plurality of first mask patterns are separated from one another by a space located therebetween, in a direction parallel to a main surface of the substrate, forming a plurality of capping films formed of a first material having a first solubility in a solvent on sidewalls and a top surface of the plurality of first mask patterns. The method further includes forming a second mask layer formed of a second material having a second solubility in the solvent, which is less than the first solubility, so as to fill the space located between the plurality of first mask patterns, and forming a plurality of second mask patterns corresponding to residual portions of the second mask layer which remain in the space located between the plurality of first mask patterns, after removing the plurality of capping films and a portion of the second mask layer using the solvent.

Provided are a mask pattern including a self-assembled molecular layer, a method of forming the same, and a method of fabricating a semiconductor device. The mask pattern includes a resist pattern formed on a semiconductor substrate and the self-assembled molecular layer formed on at least a sidewall of the resist pattern. To form the mask pattern, first, the resist pattern is formed with openings on an underlayer covering the substrate to expose the underlayer to a first width. Then, the self-assembled molecular layer is selectively formed on a surface of the resist pattern to expose the underlayer to a second width smaller than the first width. The underlayer is etched using the resist pattern and the self-assembled molecular layer as an etching mask to obtain a fine pattern.
