摘要:
A resist pattern-forming method includes applying a photoresist composition directly or indirectly on a front face of a substrate to form a photoresist film. A topcoat layer is laminated directly or indirectly on a front face of the photoresist film. The photoresist film is subjected to liquid immersion lithography in a presence of a liquid immersion liquid on a front face of the topcoat layer. Part of the topcoat layer is removed after subjecting the photoresist film to the liquid immersion lithography. The photoresist film is developed after the part of the topcoat layer is removed.
