Abstract:
PROBLEM TO BE SOLVED: To provide an improved composite material, a lithography apparatus including the composite material, and a method for producing the composite material. SOLUTION: The lithography apparatus includes: a lighting system configured so as to control radiation beams and a support member configured so as to support a patterning device. The patterning device can form patterned radiation beams by providing a pattern to the cross section of radiation beams. The lithography apparatus further includes: substrate table configured so as to hold a substrate and a projection system configured to project patterned radiation beams on a target part of the substrate. The lithography apparatus can include a composite material in which a carbon fiber layer 11 and a titanium layer 15 are provided. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus including a projection system including a movable optical element. SOLUTION: The movable optical element M4 can affect the position quantity of a radiation beam projected by the projection system by being displaced. A control device Con which drives an optical element actuator ACT is provided to influence the position quantity of the movable optical element, and consequently the position quantity of the radiation beam projected by the projection system is influenced. The control device moves the movable optical element to position the radiation beam projected by the projection system on a substrate, or corrects the position quantity of the radiation beam projected by the projection system which is caused by disturbance of an arbitrary type to the projection system.
