Patent ID: 7675633

Claim:
A method for measuring structures ( 3 ) on a substrate ( 2 ) with a coordinate measuring machine ( 1 ), wherein the coordinate measuring machine ( 1 ) comprises at least one camera defining a measurement window, at least one illumination means, at least one measurement objective defining an optical axis, and a measurement table movable in the X-coordinate direction and in the Y-coordinate direction, with which the structure to be measured is moved into the optical axis of the measurement objective, and wherein a predefined measuring method is used for measuring at least one structure ( 3 ) on the substrate ( 2 ), characterized by the further steps of: predefining a measuring method consisting of several processes, wherein a process is designed such that the measurement table is moved in the X-coordinate direction and/or in the Y-coordinate direction so that the at least one structure to be measured is within the measurement window of the camera, wherein the plurality of processes are linked with the coordinate system ( 1 a ) of the coordinate measuring machine ( 1 ); measuring the position and/or width of a structure ( 3 ) on the substrate ( 2 ) for the substrate ( 2 ) with a first orientation of the coordinate system ( 2 a ) of the substrate ( 2 ) with respect to the coordinate system ( 1 a ) of the coordinate measuring machine ( 1 ) with the measurement window of the camera in a further process; determining a deviation of at least one second orientation of the coordinate system ( 2 a ) of the substrate ( 2 ) from the first orientation; and measuring the position and/or width of a structure ( 3 ) on the substrate ( 2 ) with the measurement window of the camera, wherein the measurement window is positioned corresponding to the deviation of the first orientation from the at least second orientation such that, based on the detected second orientation of the substrate, the processes are changed for the substrate measured in the original orientation such that, on the substrate in the at least one other orientation, the same structure is measured at the same location of the structure and with the same measurement window.
