Photoresist resin composition and method of forming patterns by using the same

摘要

A method for forming a pattern includes forming a photosensitive film by coating a photosensitive resin composition on a substrate, exposing the photosensitive film to light through a mask that includes a light transmission region and a non-light transmission region, coating a developing solution on the photosensitive film, and forming a photosensitive film pattern by baking the photosensitive film, wherein the photosensitive resin composition includes an alkali soluble base resin, a photoacid generator and a photoactive compound.
