Lithographic apparatus and device manufacturing method
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 increased by a factor equal … 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 … 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 WitrynaDie Immersionslithografie ist die gängigste Technik, um integrierte Schaltkreise mit Strukturgrößen von 28 nm bis zu 10 nm in der industriellen Massenproduktion zu … Witryna29 lis 2016 · A modern immersion lithography tool, a scanner, is shown schematically in Fig. 1 such that the different basic elements are visible.
