Abstract:
A method of forming patterns of a semiconductor device may include forming a photoresist layer that includes a photo acid generator (PAG) and a photo base generator (PBG), generating an acid from the PAG in a first exposed portion of the photoresist layer by first-exposing the photoresist layer, and generating a base from the PBG in a second exposed portion of the photoresist layer by second-exposing a part of the first exposed portion and neutralizing the acid. The method may also include baking the photoresist layer after the first and second-exposing and deblocking the photoresist layer of the first exposed portion in which the acid is generated to form a deblocked photoresist layer, and forming a photoresist pattern by removing the deblocked photoresist layer by using a developer.
