Abstract: A method of manufacturing a semiconductor device includes forming a feature layer on a substrate, forming a plurality of reference patterns, arranged at a first pitch, on the feature layer, forming an organic liner on a side wall of each of the plurality of reference patterns, forming a plurality of buried patterns on the organic liner, removing the organic liner exposed between the plurality of buried patterns and the plurality of reference patterns, and etching the feature layer by using the plurality of buried patterns and the plurality of reference patterns as etch masks to form a feature pattern. Each of the plurality of buried patterns covers a space between side walls of two adjacent reference patterns among the plurality of reference patterns.

Abstract: A rinse solution includes a surfactant and deionized water. The surfactant includes a compound having a branched structure, the compound having a branched structure including a hydrophobic group-containing main chain and a plurality of side chains that are branched from the main chain and have at least one hydrophilic functional group. A method of fabricating an integrated circuit device includes forming a photoresist pattern, followed by applying the rinse solution onto the photoresist pattern.
