  • Patent number: 9341807
    Abstract: A gravitation compensator for mounting optical elements in a projection exposure apparatus and a corresponding projection exposure apparatus are disclosed. The gravitation compensator at least partly compensates for the weight force of a mounted optical element and simultaneously enables a change in the position of the optical element without the compensated weight force being altered in an impermissible manner during the change in position. This applies, in particular, to high weight forces which are to be compensated. Furthermore, the gravitation compensator enables use in different atmospheres and the compensation of corresponding aging effects.

  • Patent number: 9298101
    Abstract: A multi facet mirror of a microlithographic projection exposure apparatus includes a plurality of mirror facet units. Each unit includes a mirror member with a body, a reflective coating provided at one end of the body and an actuating surface provided at an opposite end. The unit further includes a rest member on which the actuating surface rests while the mirror member is not moving, and an actuator that tilts the mirror member about a tilting axis. The actuator has a contact surface and a lifting member which moves the actuating surface along a lifting direction. In a first operating state of the lifting member the actuating surface rests on the rest member and in a second operating state on the contact surface. A displacement member displaces the contact surface along a lateral direction only while the lifting member is in the second operating state.

  • Patent number: 8810934
    Abstract: The present disclosure relates to a method for the production and/or adjustment of an optical arrangement of a projection illumination system, in which at least one actuator is used to set the position of at least one optical element to be manipulated by moving the optical element incrementally with a specific increment size. The increment size of the movement increments is set as a function of the distance of the optical element from the desired position, with the distance being represented by a distance value. If the distance value is above a first threshold value, a substantially constant increment size is set, while the specific increment size decreases as the distance from the desired position decreases if the distance value is below the first threshold value. Alternatively or additionally, a pre-specified deviation from the specific increment size and/or from a pre-specified increment size change rate results in a warning signal and/or ceasing of the movement.

  • Patent number: 8514371
    Abstract: An imaging device in a projection exposure machine for microlithography has at least one optical element and at least one manipulator, having a linear drive, for manipulating the position of the optical element. The linear drive has a driven subregion and a nondriven subregion, which are movable relative to one another in the direction of a movement axis. The subregions are interconnected at least temporarily via functional elements with an active axis and via functional elements with an active direction at least approximately parallel to the movement axis.
