Claim One:
1. A lithographic system, comprising: a support structure configured to support a patterning device, the patterning device configured to impart a 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, the at least one exposed target field being exposed in accordance with pre-specified exposure information; and a measurement station configured to measure an attribute of the at least one exposed target field, the at least one exposed target field being measured by the measurement station to assess deformation of the at least one exposed field induced by thermal effects of the exposure; and a controller configured to determine corrective information based on the measured field deformation and to adjust the pre-specified exposure information, based on the corrective information, to compensate for the thermally-induced field deformation, wherein the exposure information includes exposure energy information, or exposure time information, or both.
