    Abstract: A positioning device comprising an object table and a positioning module configured to position the object table. The positioning module comprises a first positioning module member configured to hold the object table, a second positioning module member configured to support the first positioning module member, and a support frame configured to support the second positioning module member. The positioning module also includes one or more actuators, a position measurement system configured to measure a position of the object table, and a control unit configured to control a position of the object table based on the measured position of the object table. The control unit is further configured to control a vertical position of the second position module member so as to maintain a top surface of the second positioning module member substantially parallel to a bottom surface of the first positioning module member.

    Abstract: A lithographic apparatus including a substrate table position measurement system and a projection system position measurement system to measure a position of the substrate table and the projection system, respectively. The substrate table position measurement system includes a substrate table reference element mounted on the substrate table and a first sensor head. The substrate table reference element extends in a measurement plane substantially parallel to the holding plane of a substrate on substrate table. The holding plane is arranged at one side of the measurement plane and the first sensor head is arranged at an opposite side of the measurement plane. The projection system position measurement system includes one or more projection system reference elements and a sensor assembly. The sensor head and the sensor assembly or the associated projection system measurement elements are mounted on a sensor frame.

    Abstract: A lithographic apparatus having a substrate table, a projection system, an encoder system, a measurement frame and a measurement system. The substrate table has a holding surface for holding a substrate. The projection system is for projecting an image on the substrate. The encoder system is for providing a signal representative of a position of the substrate table. The measurement system is for measuring a property of the lithographic apparatus. The holding surface is along a plane. The projection system is at a first side of the plane. The measurement frame is arranged to support at least part of the encoder system and at least part of the measurement system at a second side of the plane different from the first side.
