    摘要: A lithographic apparatus includes an illuminator configured to condition a beam of radiation and a support configured to hold a patterning device. The patterning device is configured to pattern the beam of radiation according to a desired pattern. The lithographic apparatus also includes a substrate table configured to hold a substrate and a projection system configured to project the patterned beam onto a target portion of the substrate to form a patterned image on the substrate. The apparatus further includes a sensor configured and arranged to intercept a portion of the beam and to measure a transmission of the beam through at least a portion of the patterning device.

    摘要: 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.
