WebLithographic processes such as photolithography, soft lithography, and nanoimprint lithography are performed using masks to develop patterns. Electron beam lithography focused ion beam lithography and scanning probe lithography was performed without the use of masks ( Jose Varghese et al., 2024 ). WebContact lithography offers high resolution (down to about the wavelength of the radiation), but practical problems such as mask damage and resulting low yield make this process unusable in most production environments. Proximity printing reduces mask damage by keeping the mask a set distance above the wafer (e.g., 20 μm).
