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 17):
The exposure apparatus according to  claim 11 , further comprising:\n an aerial image measurement device that detects, via a slit pattern, an image projected via the projection optical system and the liquid of the liquid immersion area, the slit pattern being disposed on the upper surface of the second stage, wherein in a detection of the image, the positional information of the second stage is measured by the second encoder system, and the controller controls the second drive system so that the image is projected on the slit pattern following movement of the second and the third stages that have come close together, and the scanning exposure is performed following the detection of the image.
