A lithographic apparatus includes a projection system, a substrate table, a plurality of sensors, an actuator and a controller. The projection system is configured to project a patterned beam of radiation onto a substrate. The substrate table is configured to support the substrate and to move relative to the projection system. The plurality of sensors is configured to measure a deformation of the substrate table. The actuator is configured to deform the substrate table. The controller is configured to control the actuator to deform the substrate table based on measurements made by the sensors. The plurality of sensors is located on a first side of the substrate table opposite to a second side of the substrate table facing the projection system. The plurality of sensors is substantially stationary relative to the projection system.

摘要:
A lithography apparatus comprises a projection system arranged to transfer a pattern from a patterning device onto a substrate, a carrier, and a drive system for moving the carrier relative to the projection system in a plane defined by reference to orthogonal axes X and Y. The drive system comprises a shuttle moving parallel to the Y-axis, a shuttle connector connecting the shuttle to the carrier, the shuttle connector allowing movement of the carrier in a direction parallel to the X-axis relative to the shuttle, and a shuttle driver driving movement of the shuttle parallel to the Y-axis. The shuttle is located to one side of the carrier in a direction parallel to the X-axis and it is desirable if only one of the shuttle is connected to the carrier.
