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… Webperformance of the bi-layer DARC scheme versus BARC only with a 1.35 NA immersion lithography process. The process window comparison is shown in Fig. 1 for a 90 nm pitch line/space pattern. The minimum line width with a robust process window is 30 nm for bi-layer DARC as compared to 35 nm for the BARC only scheme.
