WebIn this study, the blanket etch rates of BARC and gap fill materials used in ArF lithography were examined as a function of the polymer structure, including the dextrin ester polymer. This concept was first demonstrated with the development of BARC and gap fill materials using dextrin with a-glycoside bonds in a polysaccharide. Our goal in this Webover 10 times higher SC-1 resistance than that of conventional BARC. And this novel BARC can be applied both ArF & KrF lithography process because of broad absorbance, high etching rate, chemical resistance (SC-1, SC-2, DHF, and others) and good film thickness uniformity. In this paper, we will discuss the detail of new self-crosslinking BARC in

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. 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.
