Abstract
An inventive mirror system for use in providing reflected X-ray radiation to a mask having pattern areas and opaque areas, comprising a plurality of parallel mirror segments which are vertically positioned with respect to each other at distances approximately equal to the widths of the corresponding opaque mask areas. In operation, radiation incident on each of the mirror segments is reflected to the patterned feature areas of the mask and skips over the opaque mask areas.
