Abstract:
A controller of an exposure apparatus is coupled to an alignment system, an aerial image measurement device and an encoder system, to control a drive system based on correction information and measurement information of the encoder system, the correction information compensating a measurement error of the encoder system that occurs due to a plurality of scale members. In an exposure operation of a substrate, a detection operation of a mark of the substrate and a fiducial mark, and a detection operation of an aerial image, the positional information of the stage is measured with the encoder system. In the exposure operation, the substrate is placed facing a lower surface of a nozzle member by a stage, and alignment between a pattern image and the substrate is performed based on detection information of the alignment system and the aerial image measurement device.

Claim (Index 10):
The exposure apparatus according to  claim 2 , wherein\n in the exposure operation, another head that is different from the at least three heads faces one of the plurality of scale members, instead of one head of the at least three heads, as the second stage is moved, and the positional information of the second stage is measured by at least three heads that include at least two remaining heads and the another head, the at least two remaining heads excluding the one head of the at least three heads used previously.
