Abstract
A new high-resolution soft x-ray reflectometer system utilizing a laser-plasma light source is described. This reflectometer is used to measure the reflectance of multilayer-coated optics for projection lithography. A detailed description of the instrument is presented, along with recent results obtained for a variety of soft x-ray multilayer coatings, multilayer-coated figured optics, and patterned x-ray reflection masksKeywords
