Witryna화학공학소재연구정보센터(CHERIC) 액침 노광(液浸露光, 영어: Immersion Lithography)은 렌즈와 웨이퍼 표면 사이의 공간을 굴절률이 큰 액체의 매질로 대체하여 포토리쏘그래피의 분해능을 증가시키는 기술이다. 액체의 굴절률이 늘어남에 따라 각도 분해능도 늘어나게 된다. 최근의 액침 노광 장치들은 이 액체로 순도 높은 물을 사용하여 37 나노미터 이하의 폭에 도달했다. ASML Holding, Nikon, Canon만이 액침 노광을 사용하는 …
WitrynaImmersion lithography is now in use and is expected to allow lenses to be made with numerical apertures greater than 1.0. Lenses with NAs above 1.2 or 1.3 seem likely. If an immersion fluid with a refractive index closer to that of the photoresist can be found, numerical apertures of up to 1.5 might be possible.

WitrynaSilicone immersion oil is used for deep observations of live specimens. Silicone oil (ne≒1.40) closely matches the refractive index of cells (ne≒1.38) thereby minimizing spherical aberration when imaging through thick biological samples, resulting in bright, high-resolution images. Unlike water, silicone oil exhibits virtually no ...
