Abstract
A method of manufacturing a semiconductor device includes: forming a resist layer on an underlayer, forming an exposed pattern in the resist layer, wherein the exposed pattern comprises a soluble layer and an insoluble layer, forming a resist pattern by removing the soluble layer from the resist layer in which the exposed pattern is formed, removing an intermediate exposed area from the resist pattern, forming a new soluble layer in a surface of the resist pattern from which the intermediate exposed area is removed by applying a reaction material to the resist pattern from which the intermediate exposed area is removed, wherein the reaction material generates a solubilization material that solubilizes the resist pattern, and removing the new soluble layer from the resist pattern.
