Zusammenfassung: | PURPOSE: A method of forming a micropattern is provided to improve LWR(Line Width Roughness) by forming a line-and-space pattern using a negative tone developer. CONSTITUTION: A photoresist(130) is spread on a substrate(110). The photoresist is exposed to outside by corresponding to the pattern of a line-and-space The non-exposure unit of the photoresist is removed using a negative tone developer to form the line-and-space pattern. The space of a spin-on-oxide material is formed in the side wall of the line-and-space pattern. The line-and-space pattern is removed by the developer. |
