    摘要: A method for determining the positions of structures (3) on a mask (2) is disclosed. The method is implemented in a metrology tool (1) comprising a measurement table (20) which is movable in X-coordinate direction and Y-coordinate direction. A first intensity profile (IX) is recorded along a first measurement direction (MRX), which is parallel to the X-coordinate direction. A second intensity profile (IY) is recorded along a second measurement direction (MRY), which is parallel to the Y-coordinate direction. A two-dimensional position of a centre of gravity (S) with respect to the coordinate system of the metrology tool (1) is determined from the first intensity profile (IX) and the second intensity profile (IY).
