A method of manufacturing a semiconductor device, which includes forming a resist layer on a substrate, performing an exposure and development process on the resist layer to form a resist pattern, performing a slimming process to slim the resist pattern, forming a mask material layer on side walls of the slimmed resist pattern, and removing the slimmed resist pattern. The slimming process further includes coating an extensive agent on the substrate, expanding the expansive agent, and removing the expanded expansive agent. |
