  • Publication number: 20070222979
    Abstract: A method according to an embodiment includes obtaining calibration measurement data, with an optical detection apparatus, from a plurality of marker structure sets provided on a calibration substrate. Each marker structure set includes at least one calibration marker structure created using different known values of the process parameter. The method includes obtaining measurement data, with the optical detection apparatus, from at least one marker structure provided on a substrate and exposed using an unknown value of the process parameter; and determining the unknown value of the process parameter from the obtained measurement data by employing regression coefficients in a model based on the known values of the process parameter and the calibration measurement data.

  • Publication number: 20050264790
    Abstract: A lithographic apparatus comprises an illumination system for providing a projection beam of radiation and a support structure for supporting a patterning device which impart the projection beam with a pattern in its cross-section. The patterning device has a non-flat critical dimension (CD) profile across its width. A projection system projects the patterned beam onto a target portion of a substrate. Dose variation device for varying the radiation dose across the width of the target portion compensates for the non-flat CD profile of the patterning device.
