WitrynaIn immersion lithography a higher refractive index liquid (e.g., UPW, index n = 1.44) is placed between the final lens and the wafer (replacing the lower index air, index n = 1). The higher refractive index of the DI water delivers two benefits: improved resolution and increased depth of focus of up to 50 percent for printing the finer circuit ... Witryna1 lut 2010 · Immersion lithography [1-4] has changed the way we view defectivity issues at the wafer edge significantly. During the immersion exposure sequence, the wafer edge is in contact with the water from the immersion hood (IH), introducing additional concerns beyond direct contact of resist with the scanner. ...
