The progress of immersion lithography toward the 22nm production node is putting more stringent requirements on the diffractive optics that are used for off-axis illumination. Tighter tolerances on pole balance, stray light, zeroth order, optical tra

As photolithographic tools are pressed to print the ever shrinking features required in todays devices, complex off-axis illumination is taking an ever increasing role in meeting this challenge. This, in turn, is driving tighter, more stringent req
