发明名称 Lithographic apparatus and device manufacturing method with reduced scribe lane usage for substrate measurement
摘要 In a device manufacturing method and lithographic apparatus wherein a pattern is transferred from a patterning device onto a substrate, a measurement target is provided on the substrate in a process enabling execution of a substrate measurement using radiation of a first wavelength. Subsequently the measurement target is transformed in a grid of conducting material, the grid having grid openings which are smaller than the first wavelength. The space in the scribe lane where the measurement target was, is now shielded and may be used again in further layers or processing steps of the substrate.
