Abstract:
A projection lens is disclosed for imaging a pattern arranged in an object plane of the projection lens into an image plane of the projection lens via electromagnetic radiation having an operating wavelength λ from the extreme ultraviolet range. The projection lens includes a multiplicity of mirrors having mirror surfaces arranged in a projection beam path between the object plane and the image plane so that a pattern of a mask in the object plane is imagable into the image plane via the mirrors. A first imaging scale in a first direction running parallel to a scan direction is smaller in terms of absolute value than a second imaging scale in a second direction perpendicular to the first direction. The projection lens also includes a dynamic wavefront manipulation system for correcting astigmatic wavefront aberration portions caused by reticle displacement.

Claim (Index 1):
A projection lens configured to image a pattern of a reticle in an object plane of the projection lens into an image plane of the projection lens via radiation having an EUV operating wavelength, the projection lens comprising:\n a multiplicity of mirrors, each mirror having a surface in a projection beam path between the object plane and the image plane so that the pattern of the reticle in the object plane is imagable into the image plane via the mirrors; and a dynamic wavefront manipulation system configured to correct astigmatic wavefront aberration portions caused by reticle displacement in a direction perpendicular to the object plane, wherein a first imaging scale in a first direction parallel to a scan direction is smaller in terms of absolute value than a second imaging scale in a second direction perpendicular to the first direction.
