Extreme ultraviolet lithography (also known as EUV or EUVL) is an optical lithography technology used in semiconductor device fabrication to make integrated circuits (ICs). It uses extreme ultraviolet (EUV) wavelengths near 13.5 nm, using a laser-pulsed tin (Sn) droplet plasma, to produce a … Meer weergeven In the 1960s, visible light was used for IC-production, with wavelengths as small as 435 nm (mercury "g line"). Later UV light was used, with wavelength of at first 365nm (mercury "i line"), then excimer wavelengths … Meer weergeven The tool consists of a laser-driven tin (Sn) plasma light source, reflective optics comprising multilayer mirrors, contained within a hydrogen gas ambient. The hydrogen is … Meer weergeven Reflective optics A fundamental aspect of EUVL tools, resulting from the use of reflective optics, is the Meer weergeven Assist features Assist features are often used to help balance asymmetry from non-telecentricity at different slit positions, due to different illumination … Meer weergeven EUV photomasks work by reflecting light, which is achieved by using multiple alternating layers of molybdenum and silicon. This is in contrast to conventional photomasks which work by blocking light using a single chromium layer on a quartz substrate. … Meer weergeven Neutral atoms or condensed matter cannot emit EUV radiation. Ionization must precede EUV emission in matter. The thermal production of multicharged positive ions is only possible in a hot dense plasma, which itself strongly absorbs EUV. As of 2016, the … Meer weergeven EUV light generates photoelectrons upon absorption by matter. These photoelectrons in turn generate secondary electrons, which slow down before engaging in chemical reactions. At sufficient doses 40 eV electrons are known to … Meer weergeven WebThe process of photolithography has been performed since at least the 1950s in the manufacturing of circuit boards and discrete electronic devices, initially using cyclized rubber-based photoresists as the patterning medium using contact lithography, where the photomask is brought into contact or near-contact with the substrate for direct 1:1 …
