Abstract:
An exposure apparatus that exposes a substrate is provided. The apparatus comprises a stage configured to hold and move the substrate, and a controller configured to control focus driving of the stage based on a measurement value and a correction value obtained for the focus driving of the stage for a shot region on the substrate. The controller is configured to determine the correction value in accordance with an angle of view at a time of exposure.

Claim (Index 10):
The method according to  claim 9 , wherein the determining the correction\n value includes performing actual measurement which repeatedly performing the following for each shot region for each of the plurality of angles of view: (a) performing focus measurement to obtain a measurement value for the focus driving of the stage, (b) performing focus driving in accordance with the obtained measurement value, and (c) performing focus measurement after the completion of the focus driving and calculating a residual of a target value of the measurement value obtained by the focus measurement, and calculating the plurality of correction formulas based on the residual of each shot region obtained for each of the plurality of angles of view by the actual measurement.
