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 34):
An optical system arranged between a first surface and a second surface, the optical system comprising:\n a first optical system situated between the first surface and the second surface and defining an optical axis; and a second optical system situated between the first surface and the second surface to form an image of an object, wherein the second optical system includes an optical element that is decentered from the optical axis.
