Abstract:
A catoptric system for EUV lithography includes six freeform reflective surfaces that are specified based on fringe Zernike polynomials. Each of the surfaces is tilted and/or decentered in a meridian plane and with respect to a common axis so that image and object planes are parallel. Rectangular fields can be imaged with image space numerical aperture of at least 0.5.

Claim (Index 14):
The catoptric optical system of  claim 13 , wherein:\n each of the first and fourth mirrors comprise a concave reflective surface; and each of the second and third mirrors comprise a convex reflective surface.
