WebThere are many types of lithography with practical resolution limits ranging 20–2500nm. The types of NIL are X-ray proximity, ion beam projection, electron beam, UV-proximity photolithography, deep-UV projection, extreme ultraviolet (EUV) interface lithography, EUV projection, UV nanoimprint, thermal nanoimprint, and soft lithography. WebNanoimprint lithography (NIL) is a method of fabricating nanometer scale patterns. It is a simple nanolithography process with low cost, high throughput and high resolution. It … Web29 nov. 2016 · So if an electron were accelerated to an energy of 10 keV, then it would have λ = 0.12 A. This clearly shows that if lithography could be done with electrons, it would have a huge advantage over current optical lithography systems, which are limited by their wavelength. This is just a theoretical limit, however. dessert catering winnipeg
