Abstract: The inventive concepts provide methods of forming a semiconductor device. The method includes forming a neutral layer having a photosensitive property and a reflow property on an anti-reflective coating layer, performing an exposure process and a development process on the neutral layer to form a preliminary neutral pattern at least partially exposing the anti-reflective coating layer, heating the preliminary neutral pattern to form a neutral pattern, forming a block copolymer layer on the neutral pattern, and heating the block copolymer layer to form a block copolymer pattern. The block copolymer pattern includes a first pattern disposed on the anti-reflective coating layer exposed by the neutral pattern, and a second pattern disposed on the neutral pattern and chemically bonded to the first pattern.

Abstract: Methods of forming patterns are provided. The methods may include sequentially forming an etch-target layer and a photoresist layer on a substrate, exposing two first portions of the photoresist layer to light to transform the two first portions into two first photoresist patterns and exposing a second portion of the photoresist layer to light to transform the second portion into a second photoresist pattern disposed between the two first photoresist patterns. The method may also removing portions of the photoresist layer to leave the two first photoresist patterns and the second photo resist pattern on the etch-target layer such that the etch-target layer is exposed.
