    摘要: A test mask 1 for microscopy is disclosed, which is formed on a substrate of quartz. The test mask 1 comprises a multiplicity of sub-masks 4, which are implemented such that each sub-mask 4 comprises structures which differ within a sub-mask 4 with regard to form and size. In addition, the structures of the individual sub-masks 4 are designed for optical or particle optical measurements according to size.

    摘要: A measuring system is disclosed with enhanced resolution for periodic structures on a substrate for semiconductor manufacture. Aperture structures of varying geometries are provided in the illumination beam path. The aperture structures differ regarding the transmission characteristics of light, and which adjust the intensity distribution of the diffraction orders in the imaging pupil of the optical system.
