SpletSo if a new lithography tech requires vacuum, mirrors and a new source, you might as well do it right and jump down to 13.5nm. This step has taken 15 or so years and required entire industries to be developed to achieve 13.5nm lithography, including two EUV steps would be very costly due to the costs of developing an EUV source alone. SpletLithography is used to develop nanostructures via a physical or chemical top-down approach. Chemical lithography is carried out using acid or bases or by using a heating …
