  • Inspection method and apparatus, lithographic apparatus, lithographic processing cell and device manufacturing method
    Patent number: 8804123
    Abstract: Determining line edge roughness comprises reflecting at least one radiation beam off the object, observing a first optical response signature from a beam reflected from the object, or a component thereof, being polarized with an electrical vector in a first orientation relative to the object; and observing a second optical response signature from a beam reflected from the object, or a component thereof, being polarized with an electrical vector in a second orientation relative to the object. Line edge roughness can then be determined from the two optical response signatures.
