Author Affiliations +
This paper presents an approach to designing all-reflective, projection cameras for EUV lithography. We make a comparison of fourmirror cameras with numerical apertures ranging from 0.1 to 0.2 and ring-field widths from 1.0 to 3.6 mm. Additionally, we present two theoretical models that allow for the phase change introduced by multilayer coatings
