In a method of forming patterns, an object layer is formed on a substrate. Guide patterns are formed on the object layer. A brush layer is formed using a brush polymer on surfaces of the guide patterns. The brush polymer includes at least one of a first brush polymer and a second brush polymer. The first brush polymer includes a hydrophobic repeating unit and a hydrophilic terminal group having at least two hydroxyl groups. The second brush polymer includes a hydrophobic repeating unit and a hydrophilic random repeating unit having a hydroxyl group. A self-aligned layer is formed using a block copolymer on the brush layer to form blocks aligned around the guide patterns. At least a portion of the blocks is transferred to the object layer.

Methods of forming patterns of semiconductor devices

A method of forming a pattern of a semiconductor device includes forming a lower film on a substrate having a first surface and a second surface at different levels, forming an upper film of hydrophobic material on the lower film, forming a block copolymer film on the upper film, phase-separating the block copolymer film to form first patterns spaced apart from one another and a second pattern spanning the first patterns and interposed between a bottom surface of each of the first patterns and the upper film, removing the first patterns, and performing an etch process using the second pattern or a residual part of the second pattern as an etch mask.
