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.
