Paper Abstract

We have developed a 3D practical lithography simulation system and realized the practical parameter optimization. A very fast 3D profile computation is performed by using the FFT algorithm in aerial images and the post exposure bake. The optimization system is developed by using object- oriented technology in order to reduce the computation time. The resulted computational time is less than one tenth of the conventional system. The total parameter optimization time is also reduced.
