I thought the competition was between Zeiss, Nikon and Canon lenses. Does Leica make lenses for lithography systems that compete against ASML? Sam

You need to define "best". Mininmum feature size? Depth of focus? Feature size uniformity ( x vs y )? Feature size uniformity through focus? Those are dimensional aspects of best. Location/placement variations are also important in semiconductor fabrication..and so the lenses in the scanners. And then there is field size. ZEISS is sole supplier to ASML scanners/steppers except the residual remains of what they obtained from SVGL/Perkin Elmer although Tinsley optics was spun out for defense reasons. Canon and Nikon make their own lenses. Leica makes good (small) field lenses and has several dominant metrology tool products. Leica comes from Leitz and Cambridge merger. Not a player in the "printing" side cheers ti2
