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 WebThe BARC used for this project is an organic film that has absorbing properties. Therefore, the optical extinction coefficient (k) will have a profound effect on the lithography system and cannot be ignored. The complex refractive index can be represented by the following equation: n*=fl+jk software rbo
