Photoresist composition and method of forming photoresist pattern
A method of forming a photoresist pattern includes forming a protective layer over a photoresist layer formed on a substrate, and selectively exposing the photoresist layer to actinic radiation. The photoresist layer is developed to form a pattern in the photoresist layer, and the protective layer is removed. The protective layer includes a polymer having fluorocarbon pendant groups.
