    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).

    摘要: A method is disclosed which is suitable for the calibration of a measuring table (20) of a coordinate measuring machine (1). For this purpose, a mask (2) is deposited in a three-point support of the measuring table (20), wherein the mask (2) used for the calibration of the measuring table (20) is a mask (2), which is used for the semiconductor production. The measurement of positions of a plurality of different structures (3) which are arranged in a distributed manner on the mask (2) is carried out. The structures (3) are available in an initial orientation on the mask (2). The mask (2) is rotated and the position of the structures (3) is determined in the rotated orientation. Afterwards, the mask (2) is shifted and the position of the structures (3) is also determined. A total correction function for eliminating coordinate-dependant measuring errors is determined, wherein the total correction function has a first correction function and a second correction function.
