GRADED TOPCOAT MATERIALS FOR IMMERSION LITHOGRAPHY |
摘要 |
A topcoat material for immersion lithography and a method of performing immersion lithography using the topcoat material. The topcoat material includes a mixture of a first polymer and a second polymer. The first and second polymers of the topcoat material, when the topcoat material is formed into a topcoat layer between an immersion fluid and a photoresist layer, disperse non-homogenously throughout the topcoat layer.
