Photolithography material for immersion lithography processes
A photolithography material is provided. The photolithography material is a surface modifying material. The photolithography material includes a polymer (e.g., fluorine polymer) that includes less than approximately 80% hydroxyl groups. In an embodiment, the photolithography material includes less than approximately 80% fluoro-alcohol functional units. Methods of using the photolithography material include as an additive to a photoresist or topcoat layer. The photolithography material may be used in an immersion lithography process.
