Paper Abstract

We report bubble scattering effects on photoresist when a 193nm immersion interferometric lithographic system is employed. According to Mie theory and FDTD simulation, the scattering effect of a bubble becomes significant and may cause defects on a resist pattern when its diameter is greater than 60nm. Some preliminary experimental results are also included.
