    摘要: The present invention relates to a reference-beam interferometer for determining the position of a traversable stage, wherein an evacuated tube is inserted into the longer of the two interferometer legs. The tube is closed off by windows, which have a negative coefficient of thermal expansion and which can have a coating for reflecting heat radiation. Moreover, thermal compensation plates are inserted into the shorter of the two beam paths.

    摘要: A method for determining the centrality of masks is disclosed. The mask is positioned in a coordinate measuring device on a measurement table displaceable in a direction perpendicular to the optical axis of an imaging measurement system in an interferometrically measurable way. The position of a mask coordinate system with respect to the measuring device coordinate system is determined based on at lest two structures on the mask. The relative distance from one of the at least first and second outer edges to the at least two structures is determined. The coordinate measuring machine determines the actual coordinates of the at least two structures with respect to the respective outer edges, which must not exceed a predetermined deviation from a desired value.

    摘要: To determine an edge bead removal line (17) on a wafer (10), first lines or edges (38, 40, 42, 44) in the edge area (19) of the wafer (10) are detected. A first line area (48) and a second line area (50) are defined on either side of these lines (38, 40, 42, 44). The structures (36) present in these edge areas (48, 50) are compared to each other. From the result of the comparison it is determined whether or not an edge bead removal line (17) is present.
