Immersion scanner ultrapure water
Witryna18 sie 2024 · Immersion lithography uses a pool of ultra-pure water between the lens and the wafer to increase the lens's numerical aperture (NA) – a measure of its ability to collect and focus light. With conventional 'dry' lithography, NA can only reach about 0.93. Immersion made it possible to create systems with an NA up to 1.35. 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. First, when the …
