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 21):
An extreme ultraviolet lithography system that creates a pattern having a plurality of parallel lines on a workpiece, the lithography system comprising:\n an optical system which forms the pattern having the plurality of parallel lines on the workpiece with an extreme ultraviolet beam from an irradiation apparatus; and a workpiece stage assembly which retains and moves the workpiece relative to the optical system along a scan direction which crosses to a pitch direction of the plurality of parallel lines of the pattern, wherein the optical system includes a pattern blind assembly which creates a shaped exposure field where the pattern is formed on the workpiece, and wherein the shaped exposure field includes a first side extending a first direction which crosses to the pitch direction and the scan direction, and a second side extending a fourth direction which crosses to the first direction, the pitch direction, and the scan direction.
