WebOct 5, 2024 · Description. Extreme ultraviolet (EUV) lithography is a soft X-ray technology, which has a wavelength of 13.5nm. Today’s EUV scanners enable resolutions down to 22nm half-pitch. In a system, an EUV light source makes use of a high power laser to create a plasma. This, in turn, helps emit a short wavelength light inside a vacuum … WebFedor G Pikus.

WebJan 2, 2024 · Sometimes the half-pitch is used. Unsurprisingly, that is half the pitch, and if the width and spacing on the layer are the same, then it will equal them both. The fundamental equation of lithography is that the resolution (half-pitch this time) is k 1 × λ ÷ NA where: k 1 is the Rayleigh parameter, which is a measure of the lithography ...

WebHowever, when electron-beam lithography approaches its resolution limit, imaging and metrology of the fabricated structures by using standard scanning electron microscopy become difficult. ... Measurements of point- and line-spread functions suggested that the resolution in fabricating sub-10 nm half-pitch structures was primarily limited by ... WebMar 20, 2015 · We have synthesized a new resist molecule and investigated its high-resolution capability. The material showed resolved line-spaces with 14 nm half-pitch (hp) and the potential to pattern 11 nm hp features. Line edge roughness values as low as 3.15 nm were seen in optimized formulations. The dose-to-size is estimated at around 20-30 …
WebThe large area wire grid polarizers (LA-WGPs) with 50 nm half-pitch were fabricated using ArF immersion lithography overcoming the limit of the shot field size. To realize the 50 nm line and space patterns on a 300 mm wafer, a zero-distance stitching process that connects the shot fields is suggested. To compensate for mutual interference between the shot …
