Web29 nov. 2016 · Conventional photolithography systems, which rely on UV light, can therefore achieve a minimum “diffraction-limited” feature size of several hundreds of nanometers. Using resolution enhancement techniques such as phase shifting and immersion lithography, it is possible to improve the resolution to some extent. WebIn photolithography, light is used to transfer patterns onto any substrate. It is basically a top-down approach. Mostly visible and ultraviolet radiations are employed in photolithography. The substrate used to produce photo-resistant coating should be free of …
