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. WebFollowing are the limitations of the µ-PIM process: • Complex process because it requires multiple steps. • Requires X-ray generation source, preparation of mask, substrate, and development of the mold. • Requires special protection for the operator against exposure to X-ray radiations. •
