High Refractive Index Immersion Fluids for 193nm Immersion Lithography
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 … 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 … Zobacz więcej Defect concerns, e.g., water left behind (watermarks) and loss of resist-water adhesion (air gap or bubbles), have led to considerations … 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 sources. Specifically, the throughput is directly proportional to stage speed V, which is related to dose D and rectangular slit … Zobacz więcej • Oil immersion • Water immersion objective Zobacz więcej Witryna8 lip 2013 · Because the development of extreme ultraviolet (EUV) lithography is behind schedule throughout the industry, TSMC will continue to use its argon fluoride (ArF) immersion lithography (which relies on 193-nm-emitting ArF excimer lasers), which the company introduced for the 40 nm process, for 28, 20, 16, and 10 nm processes. … Witryna因為在浸潤式微影（Immersion Lithography）技術上的成就，台積電奈米影像技術研究發展副總經理林本堅獲頒今年度的國際電機電子工程師學會（IEEE）西澤潤一獎（Jun … phoenix on the beach orange beach
