Abstract
A method for forming a fine photoresist pattern of a semiconductor device, the method comprising the steps of forming a chemically amplified photoresist film over an underlying layer formed over a semiconductor substrate to form a first photoresist pattern; exposing the first photoresist pattern without exposure mask to bake the resulting structure; and flowing the photoresist of the first photoresist pattern to obtain a second photoresist pattern.
