Substrate processing method, substrate processing apparatus, and storage medium |
摘要 |
A substrate processing method is performed to improve surface roughness of a pattern mask formed on a substrate by being exposed and developed. The method includes supplying a first solvent in a gaseous state to a surface of the substrate to dissolve the pattern mask, and supplying a second solvent to the surface of the substrate, which is supplied with the first solvent, to dissolve the pattern mask, wherein a permeability of the second solvent is lower than a permeability of the first solvent. |

1. A substrate processing method performed to improve surface roughness of a pattern mask formed on a substrate by being exposed and developed, the method comprising:
performing a preprocessing, the preprocessing including:
supplying a preprocessing agent to the substrate to attach a liquid film onto a surface of the pattern mask;heating the substrate to dry the liquid film; andplanarizing the surface by cohesive force generated on the surface of the pattern mask when the liquid film is dried; supplying a first solvent in a gaseous state to the surface of the substrate to dissolve the pattern mask after performing the preprocessing; and supplying a second solvent to the surface of the substrate, which is supplied with the first solvent, to dissolve the pattern mask, wherein a permeability of the second solvent is lower than a permeability of the first solvent. |
