Abstract:
A lithographic apparatus uses a height sensor to obtain height sensor data representing a topographical variation across a substrate. The height sensor data is used to control focusing of a device pattern at multiple locations across the substrate. A controller identifies one or more first areas where height sensor data is judged to be reliable and one or more second areas where the height sensor data is judged to be less reliable. Substitute height data is calculated for the second areas using height sensor data for the first areas together with prior knowledge of expected device-specific topography. The focusing of the lithographic apparatus is controlled using a combination of the height data from the sensor and the substitute height data.

Claim (Index 22):
The lithographic apparatus of  claim 8 , wherein the control system is configured to determine substitute height data for the one or more second areas using height sensor data for the one or more first areas together with prior knowledge of expected device-specific topography.
