Abstract

An EUV microscope apparatus utilizing a source of EUV light. The light is sent to a collector which creates a first focused EUV beam. A monochromator module receives the first focused EUV beam and produces a second focused EUV beam that is passed to an illumination module. The output of the illumination module is reflected off a mask. The reflected beam from the mask is sent to a zone-plate and a detector to produce an image.
