发明名称 Cleaning solution for immersion photolithography system and immersion photolithograph process using the cleaning solution
摘要 A cleaning solution for an immersion photolithography system according to example embodiments may include an ether-based solvent, an alcohol-based solvent, and a semi-aqueous-based solvent. In the immersion photolithography system, a plurality of wafers coated with photoresist films may be exposed pursuant to an immersion photolithography process using an immersion fluid. The area contacted by the immersion fluid during the exposure process may accumulate contaminants. Accordingly, the area contacted by the immersion fluid during the exposure process may be washed with the cleaning solution according to example embodiments so as to reduce or prevent defects in the immersion photolithography system.
