Abstract:
A movable stage system is configured to support an object. The stage system comprises an object table configured to support the object and an object table support defining an object table support surface configured to support the object table. The object table support comprises at least one first actuator to drive the object table support in a first driving direction substantially parallel to the object table support surface. In a projection on a plane parallel to the object table support surface the at least one actuator is spaced with respect to the object table in a direction perpendicular to the first driving direction such that the risk on slip between the object table support and the object table supported thereon is decreased.
Abstract:
A sensor includes two shear-mode piezoelectric transducers, wherein each piezoelectric transducer has a bottom surface and a top surface, wherein the top surfaces of the piezoelectric transducers are rigidly connected to each other, and wherein the bottom surfaces of the piezoelectric transducers are configured to be attached to an object to be measured.
Abstract:
A lithographic apparatus including: a first object, a second object which is moveable relative to the first object in a moving direction, a set of cables and/or tubing arranged between the first object and the second object, a guiding drum to guide the set of cables and/or tubing, the guiding drum being rotatable about a rotation axis extending perpendicular to the moving direction, a drum positioning device to position the guiding drum such that it follows movement of the set of cables and/or tubing caused by movement of the second object relative to the first object and a guiding structure to guide movement of the guiding drum in the moving direction.
Abstract:
A lithographic apparatus comprises a system. The system comprises a first part, a second part and an energy absorbing element. The second part is configured to move relatively to the first part. The system has a gap located between the first part and the second part during an operation mode of the system. The energy absorbing element is for absorbing energy between the first part and the second part when the first part and the second part crash onto each other in a failure mode of the system. The energy absorbing element is outside the gap.
