Abstract:
In an exposure operation, as a second stage is moved in a direction parallel to a predetermined plane, another head different from a plurality of heads faces a grating section instead of one head of the plurality of heads, and positional information of the second stage is measured by multiple heads including remaining heads and the another head, the remaining heads excluding the one head of the plurality of heads, and correction information is acquired for the positional information obtained from the another head, based on the positional information obtained from the plurality of heads including the one head.

Claim (Index 16):
The exposure apparatus according to  claim 15 , wherein\n the another correction information includes at least one of information to compensate for the measurement error of the second encoder system that occurs due to relative motion between the heads and the grating section in a direction different from a measurement direction of the positional information by the heads, and information to compensate for the measurement error of the second encoder system that occurs due to a difference between a position of a reference plane and a position of a grating surface of the grating section in a third direction orthogonal to the predetermined plane, the reference plane being a reference plane for position control or positioning of the second stage, or a reference plane with which the substrate coincides in the exposure operation.
