Abstract:
According to one embodiment, there is provided an exposure apparatus, including a focus detecting system, a stage, and a controller. On the stage, a substrate is to be mounted. The controller performs focus measurement on an incomplete shot area, part of which is outside a pattern forming area of the substrate, by the focus detecting system. The controller obtains amounts of defocus of a plurality of planes that are candidates for approximating the incomplete shot area according to the result of measuring the incomplete shot area. The controller decides on a plane to approximate the incomplete shot area from among the plurality of planes according to the amounts of defocus of the plurality of planes. The controller drives the stage using a focus-leveling value according to the decided-on plane so as to control a surface position of the incomplete shot area.

Claim (Index 14):
The surface position control method according to  claim 11 , wherein\n deciding on the plane to approximate the incomplete shot area includes determining a plane for which the amount of defocus in part of the pattern forming area in the incomplete shot area is within an appropriate range to be the plane to approximate the incomplete shot area, from among the plurality of planes.
