WebTARC vs BARC. Anti-reflective coatings are an essential part of photolithography with the continual shrinking of pattern geometries. Anti-reflective coatings reduce reflectivity at resist interfaces, thus providing better line width control with minimal loss of resist performance. The reflectivity is reduced by either attenuating light that ... WebThese start with a lithography operation followed by an etch or ion implantation.
