  • Patent number: 10698318
    Abstract: The invention relates to a method and a device for characterizing a mask for microlithography. In a method according to the invention, structures of a mask intended for use in a lithography process in a microlithographic projection exposure apparatus are illuminated by an illumination optical unit, wherein the mask is imaged onto a detector unit by an imaging optical unit, wherein image data recorded by the detector unit are evaluated in an evaluation unit. In this case, for emulating an illumination setting predefined for the lithography process in the microlithographic projection exposure apparatus, the imaging of the mask onto the detector unit is carried out in a plurality of individual imagings which differ from one another with regard to the illumination setting set in the illumination optical unit or the polarization-influencing effect set in the imaging optical unit.

  • Patent number: 6845174
    Abstract: An arrangement for the identification of a substrate (S) having at least one identification marking (I), comprising a turntable (2) for rotating a substrate (S) placed thereon; an illumination source (4) and a receiving device (5) for evaluating the intensity of the light emerging from the illumination source (4), the edge zone of the substrate (S) placed on the turntable (2), upon rotation thereof, influencing the light intensity striking the receiving device (5); a device (6) for reading the identification marking (I), having a sensing region (E); and a calculation device that calculates a manipulated variable for a correction rotation angle about the rotation axis (A) for alignment of the identification marking (I) with respect to the sensing region (E), and a manipulated variable for a correction motion for changing the position of the sensing region (E) with respect to the rotation axis (A) or with respect to the actual position of the identification marking (I), and outputs them to a positioning devi
