Abstract
In this paper we present a status overview of the development of 157-nm lithography. Solutions and challenges in the exposure system design are discussed. The solutions and challenges include optics, purging, and reticle handling issues. The impact of CaF2 birefringence (intrinsic and stress induced) on lens performance is evaluated. Experimental data on optical path purging and radiation cleaning is presented. The pellicle dilemma is reviewed, and feasibility of a thick glass plate pellicle is discussed. Additionally, a status summary on resist process development is given.
