17 December 2003 Effects of reticle reflectance on lithography
Author Affiliations +
We report in this work experimental and theoretical results showing the effects of absorber reflectivity on standard flare measurements, image formation and how this may contribute to various image metrics used in lithography. Our study shows that under typical conditions the reflectance from the absorber film has only a small effect on the image produced by the exposure system.
