Abstract:
An extreme ultraviolet lithography system ( 10 ) that creates a pattern ( 230 ) having a plurality of densely packed parallel lines ( 232 ) on a workpiece ( 22 ) includes a patterning element ( 16 ); an EUV illumination system ( 12 ) that directs an extreme ultraviolet beam ( 13 A) at the patterning element ( 16 ); a projection optical assembly ( 18 ) that directs the extreme ultraviolet beam diffracted off of the patterning element ( 16 ) at the workpiece ( 22 ); and a pattern blind assembly ( 26 ) positioned in a beam path ( 55 ) of the extreme ultraviolet beam ( 13 A). The pattern blind assembly ( 26 ) shapes the extreme ultraviolet beam ( 13 A) so that an exposure field ( 28 ) on the workpiece ( 22 ) has a polygonal shape.

Claim (Index 29):
The extreme ultraviolet lithography system of  claim 28 , wherein the pattern blind assembly shapes an illumination area on the patterning element.
