Abstract
A method of making a photolithographic mask includes detecting a defect in a mask blank. The mask blank includes a reflector on a substrate. The method also includes calculating a correction of an absorber pattern to be used in forming an absorber and forming an absorber on the mask blank using the absorber pattern and the calculated absorber pattern correction. The correction reduces effects of the mask blank defect on the operation of the mask.
