Methods of alignment, overlay, configuration of marks, manufacturing of patterning devices and patterning the marks

A resonant amplitude grating mark has a periodic structure configured to scatter radiation incident on the mark. The scattering is mainly by coupling of the incident radiation to a waveguiding mode in the periodic structure. The effective refractive indexes and lengths of portions of the periodic st...
