Abstract
In the past 10 years, immersion lithography has been the most effective high volume manufacturing method for the critical layers of semiconductor devices. Thinking of the next 10 years, we can expect continuous improvement on existing 300 mm wafer scanners with better accuracy and throughput to enhance the total output value per input cost. This value productivity, however, can be upgraded also by larger innovations which might happen in optical lithography. In this paper, we will discuss the possibilities and the impossibilities of potential innovation ideas of optical lithography, which are 450 mm wafer, optical maskless, multicolor lithography, and metamaterial.
