I'm not sure if this Lambda news was posted last week..............

The Fab Line

By Chad Fasca and Dylan McGrath

Lambda Physik reported it is ready to ship a new 248-nanometer excimer laser, the NovaLine Litho/S design, to provide
optimum performance for the next generation of deep-ultraviolet microlithography steppers and scanners using
high-numerical-aperture projection lenses. The company claims the laser has the highest spectral purity of any DUV excimer
laser presently available. According to the company, a key element in achieving this performance is the use of a patented
polarization coupled resonator (PCR) design. PCR improves both spectral purity and laser operating efficiency; increased
efficiency is said to extend optical component lifetimes and lengthen maintenance intervals. PCR is the result of a joint
development effort between the Tokyo-based Matsushita Research Institute of Technology and Lambda Physik.
According to Lambda Physik, the laser will be displayed at Semicon/Japan later this year, Dec. 3-5.
