A new vector optical lithography simulator, METROPOLE, is presented. Rigorous simulations run quickly on a workstation for complex 2D regular and phase shifting masks, substrate bleaching, optical metrology and alignment problems. An analysis of a novel phase shifting techniques is undertaken to highlight the usefulness of the program.<
