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. Web27 sep. 2024 · for a BARC layer (typically 25-90 nm) and BARC etch step, the etch margin is greatly improved for pattern transfer from photoresist to the DARC layer. A cost benefit would be realized by eliminating the spin-on BARC material and BARC coating process steps. 0.021 Fig. 6. Lithography simulation result of bi-layer DARC stack DARC Film …

Webbottom antireflection coating (BARC) and resist, this film stack is not controlled by the photolithography group. Thus, the lithography group must respond to these film stack changes with adjustments to the lithography process. From a lithography standpoint, the most important film stack property is the reflectivity of the substrate.
