Immersion lithography原理
WitrynaThe argon fluoride laser (ArF laser) is a particular type of excimer laser, which is sometimes (more correctly) called an exciplex laser. With its 193-nanometer wavelength, it is a deep ultraviolet laser, which is commonly used in the production of semiconductor integrated circuits, eye surgery, micromachining, and scientific research."Excimer" is … Witryna光刻版保护膜是蒙贴在铝合金框架上的一层透明薄膜，防止灰尘掉落在掩模有图形的一侧。. 有了这个薄膜的保护，灰尘颗粒只能掉落在掩模版玻璃的一侧或保护膜上。. 由于玻璃基板的厚度和保护膜距离基板的距离相近，均为 6mm 左右，所以这些吸附在掩模上的 ...

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 … Immersion lithography is a photolithography resolution enhancement technique for manufacturing integrated circuits (ICs) that replaces the usual air gap between the final lens and the wafer surface with a liquid medium that has a refractive index greater than one. The resolution is … Zobacz więcej The idea for immersion lithography was patented in 1984 by Takanashi et al. It was also proposed by Taiwanese engineer Burn J. Lin and realized in the 1980s. In 2004, IBM's director of silicon technology, Ghavam Shahidi, … Zobacz więcej The ability to resolve features in optical lithography is directly related to the numerical aperture of the imaging equipment, the numerical aperture being the sine of the maximum refraction angle multiplied by the refractive index of the medium … Zobacz więcej As of 2000, Polarization effects due to high angles of interference in the photoresist were considered as features approach 40 nm. Hence, illumination sources generally need to be … Zobacz więcej The resolution limit for a 1.35 NA immersion tool operating at 193 nm wavelength is 36 nm. Going beyond this limit to sub-20nm nodes requires multiple patterning. … Zobacz więcej Defect concerns, e.g., water left behind (watermarks) and loss of resist-water adhesion (air gap or bubbles), have led to considerations of using a topcoat layer directly on top of the photoresist. This topcoat would serve as a barrier for chemical … Zobacz więcej As of 1996, this was achieved through higher stage speeds, which in turn, as of 2013 were allowed by higher power ArF laser pulse … Zobacz więcej • Oil immersion • Water immersion objective Zobacz więcej
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.
