Inventor: WALTER PAULS
IPC: G01N21/55
Filed: 2022-04-27
Abstract: To provide a method for measuring an effect of a wavelength-dependent measuring light reflectivity and an effect of a polarization of measuring light on a measuring light impingement on a lithography mask.SOLUTION: To measure an effect of a wavelength-dependent measuring light reflectivity RRet of a lithography mask, a measuring light beam is caused to impinge on the lithography mask within a field of view of a measuring apparatus. The measuring light has a wavelength bandwidth between a wavelength lower limit and a wavelength upper limit differing therefrom. The reflected measuring light emanating from an impinged section of the lithography mask is captured by a detector. A filter with a wavelength-dependent transmission within the wavelength bandwidth is introduced into a beam path of the measuring light beam between a measuring light source and the detector. The measuring light reflected by the lithography mask is captured again by the detector once the filter has been introduced. The wavelength-dependent reflectivity RRet or an effect of the wavelength-dependent reflectivity RRet is determined on the basis of the capture results.SELECTED DRAWING: Figure 1
