Claim One:
1. A lithographic system, comprising: an illumination system configured to condition a beam of radiation; a support structure configured to support a patterning device, the patterning device configured to impart the beam of radiation with a pattern in its cross-section; a substrate holder configured to hold a substrate, the substrate comprising a plurality of target fields; a projection system configured to expose the patterned beam onto at least one of the target fields of the substrate; and a measurement station configured to measure an attribute of the at least one exposed target field, wherein the at least one exposed target field is exposed in accordance with pre-specified exposure information, the at least one exposed target field is measured by the measurement station to assess deformation of the at least one exposed field induced by thermal effects of the exposure, corrective information is determined based on the measured field deformation and the pre-specified exposure information is adjusted, based on the corrective information, to compensate for the thermally-induced field deformation.
