Lithographic processing
A single iteration of photolithography combines several steps in sequence. Modern cleanrooms use automated, robotic wafer track systems to coordinate the process. The procedure described here omits some advanced treatments, such as thinning agents or edge-bead removal. The photolithography process is carried out by the wafer track and stepper/scanner, and the wafer track syste… WebLithographic processes such as photolithography, soft lithography, and nanoimprint lithography are performed using masks to develop patterns. Electron beam lithography …
