    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: In the production of semiconductor or other components, the structures are normally manufactured in different planes. In the orientation of these planes relative to each other a displacement or alignment is examined, among other things, and detected as an overlay defect. To reduce a systematic measuring defect a measuring device (10) is provided for measuring the overlay defect. This device has an illuminating device (12), a lens or objective (14) for focusing radiation from the illuminating device (12) onto the object (16) and a tube lens (18) for imaging the radiation onto a sensor unit (20). A compensator (22), in which the wave fronts of the incident radiation are tilted with spectral variation such that the axial transverse chromatic aberration is compensated for, is provided in the path of rays of the measuring device (10).

    摘要: A metrology tool (1) for measuring the positions of structures (32) on a mask surface (31) is disclosed. On a measuring stage (33) a reflector (36) selective with respect to the wavelength is provided, which essentially reflects light within a first wavelength region emitted from a first illumination device (10), and essentially does not reflect light within a second wavelength region emitted from a second illumination device (20). The reflector (36) selective with respect to the wavelength preferentially is a dichroic mirror. By detecting the light within the first wavelength region reflected by the reflector (36) the position of predefined sections of outer edges (37) of the mask is determined. The light from the second wavelength region is used for determining the coordinates of structures on the mask. Due to the selectivity with respect to the wavelength of the reflector (36) this determination of coordinates is not perturbed by a reflection of the light within the second wavelength region from the reflector (36).
