摘要:
The invention provides a height detecting apparatus for a lithographic apparatus. The height mapping apparatus includes a height mapping unit for providing at least one height map of a top surface of an object to be placed in a radiation beam of the lithographic apparatus, the object to be clamped by a clamping force applied thereto on a support constructed to support the object. The height mapping apparatus also includes a control unit for controlling the mapping unit to provide the at least one height map of the object relative to at least two different clamping pressure levels.
