  • Patent number: 10204812
    Abstract: A method and corresponding device for the alignment of a first substrate comprising at least two first alignment marks with a second substrate comprising at least two second alignment marks. By means of a first assignment, the first alignment marks are assigned to at least two first characteristic alignment features of the first substrate in an X-direction and in a Y-direction. By means of a second assignment, the second alignment marks are assigned to at least two second characteristic alignment features of the second substrate in an X-direction and in a Y-direction, and by means of an alignment, the first and second alignment marks are aligned in relation to one another in an X- and Y-direction by means of the first and second characteristic alignment features.
