Lithography barc

Web4 apr. 2007 · For severe CD control, BARC (Bottom Antireflective Coating) has been used and this material must be used for immersion lithography. So far, we have developed several BARCs with various advantages (fast etch rate, broad resist compatibility, high adhesion, conformal...etc). 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.
