    Abstract: The invention provides a method for correcting thermally-induced field deformations of a lithographically exposed substrate. First, a model is provided to predict thermally-induced field deformation information of a plurality of fields of the substrate. The pre-specified exposure information used to configure an exposure of the fields is then modified based on the thermally-induced deformation information as predicted by the model. Finally a pattern is exposed onto the fields in accordance with the pre-specified exposure information as modified. The predicting of thermally-induced field deformation information by the model includes predicting of deformation effects of selected points on the substrate. It is based on a time-decaying characteristic as energy is transported across substrate; and a distance between the selected points and an edge of the substrate.
