WebMar 3, 2024 · So should be important for high NA, even if the illumination is just a thin ring. At NA 1.4 and 1.5 the angles are so shallow, aberrations likely get gigantic. So the condenser needs to be well made and relatively sharp, like a high NA objective - with its shallow focus depth, hence tight slide thickness. WebDec 16, 2024 · But at some point, EUV single patterning will reach the limit. Then, chipmakers must go to EUV double patterning or wait for high-NA EUV. (Today’s EUV lithography scanners incorporate a 0.33 numerical aperture lens, while high-NA lithography utilizes a 0.55 NA lens. Still in R&D, the first high-NA EUV tool is expected in 2024.)
WebSep 20, 2024 · Higher numerical apertures allow increasingly oblique rays to enter the objective front lens, producing a more highly resolved image. In practice, however, it is difficult to achieve numerical aperture values … WebFirst, place a stained specimen on the stage and rotate the nosepiece until the objective (preferably a low power 10x or 20x) is in place. Switch on the light source. Open all …
Webusing a high NA dark field condenser. High NA dark field condensers have a fixed focal length at which they optimally work. The manufacturer may recommend a slide thickness or this value may be printed on the condenser. A standard slide is 1.2 mm thick, but slides, even from the same box, vary in thickness. The slide should be no more than ± WebSep 20, 2024 · The simplest and least corrected (also the least expensive) condenser is the Abbe condenser that can have a numerical aperture up to 1.4 in high-end models with three or more internal lens elements. While …
WebDec 4, 2024 · “Similar to comparisons of EUV and immersion, high-NA has several value propositions. The first is the ability to reduce cycle time in the fab, as a single pass of high-NA will require less total processing than multiple passes of 0.33 NA EUV. The second is edge placement error.
