    摘要: 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.

    摘要: A method of forming a fine pattern includes forming pillar-shaped guides regularly arranged on a feature layer, forming a block copolymer layer on the feature layer around the pillar-shaped guides, phase separating the block copolymer layer, forming first domains regularly arranged on the feature layer with the pillar-shaped guides, forming a second domain on the feature layer surrounding the pillar-shaped guides and the first domains, removing the first domains, and forming holes corresponding with the first domains in the feature layer by etching the feature layer using the pillar-shaped guides and the second domain as etch masks. The block copolymer layer includes a polymer blend having first and second polymer blocks having first and second repeat units, respectively, a first homopolymer and a second homopolymer. The first domains include the first polymer block and the first homopolymer, and the second domain includes the second polymer block and the second homopolymer.
