Recently, considerable progress has been made in the development of ArF excimer lasers for 193 nm lithography. A line-narrowed ArF excimer laser with a bandwidth of < 0.7 pm can be used with a refractive lens system. In this paper, we present a line-narrowed ArF excimer laser which we have developed for 193 nm lithography. This laser produces an output power of over 5 W with a 0.6 pm FWHM bandwidth at 1 kHz operation.
