摘要: Provided herein is a method of forming micropatterns, including: forming an etching target film on a substrate; forming a photosensitivity assisting layer on the etching target film, the photosensitivity assisting layer being terminated with a hydrophilic group; forming an adhesive layer on the photosensitivity assisting layer, the adhesive layer forming a covalent bond with the hydrophilic group; forming a hydrophobic photoresist film on the adhesive layer; and patterning the photoresist film.
