发明名称 Method for fabricating fine pattern
摘要 A method for fabricating fine patterns includes forming a first photomask including first line patterns and first assist features and forming a second photomask including second line patterns extending to a portion corresponding to the first assist features in a direction perpendicular to the first line patterns. A first resist layer may be exposed through a first exposure process by using the first photomask, and a first resist pattern formed to open regions following the shape of the first line patterns. The first resist pattern may be frozen and a second resist layer may be formed to fill the opened regions of the first resist pattern. The second resist layer may be exposed through a second exposure process by using the second photomask, and a second resist pattern formed to open regions corresponding to the intersections between the first and second line patterns with the first resist pattern.
