Paper Abstract

Via fill performance of AR7 (KrF anti-reflectant) and a prototype 193nm anti-reflectant were measured for 600 and 1000 nm deep vias in thermal oxide. Simple fitting functions were found which gave good agreement with experimental data (Rsq over 0.84). The most important factors were AR thickness, via duty ratio and via depth. The importance of these factors was different for the different anti-reflectants.
