24 June 1993 Effects of illumination system aberrations on proximity XRL images
Author Affiliations +
The aberrations of a typical condenser system for proximity X-ray lithography are obtained through ray-tracing and their effect on the overlay and linewidth control is analyzed. The main effect of the illumination systems aberrations is run-out error due to the slope of the wavefront aberration and the error is of the order of 2 nm.
