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 22):
The extreme ultraviolet lithography system of  claim 21 , wherein the pattern having the plurality of parallel lines within a first region on the work piece is formed by moving the workpiece along the scan direction and directing the extreme ultraviolet beam at the workpiece with the optical system,\n wherein the pattern having the plurality of parallel lines within a second region on the work piece is formed by moving the workpiece along a counter scan direction opposite to the scan direction and directing the extreme ultraviolet beam at the workpiece with the optical system, and wherein the first region and the second region are overlapped.
