Liquid Composition for Immersion Lithography and Lithography Method Using the Same
摘要:
Disclosed herein are a liquid composition for immersion lithography and a lithography method using the composition. The liquid composition includes at least one nonionic surfactant selected from the group comprising of a polyvinyl alcohol, a pentaerythritol-based compound, a polymer containing an alkylene oxide, and a compound represented by Formula I: wherein R is a linear or branched, substituted C1-C40 alkyl, and n is an integer ranging from 10 to 10,000. The surface tension of the liquid composition is reduced by the nonionic surfactant, thereby solving the problem that the liquid composition is not completely filled or is partially concentrated on a wafer having a fine topology and removing micro bubbles between the photoresist film and the liquid composition.
