Abstract:
A first stage system having a first stage and a first drive system that moves the first stage is configured to hold a mask illuminated with illumination light. A second stage system having a second stage and a second drive system that moves the second stage is configured to hold a substrate. A measurement system having a first encoder system and a second encoder system measures positional information of the first and second stages, respectively. The second encoder system measures the positional information of the second stage with a plurality of heads that face a grating section. The first and second drive systems are controlled based on correction information for compensating for a measurement error of the second encoder system that occurs due to the heads and measurement information of the first and the second encoder systems.

Claim (Index 39):
The exposure method according to  claim 27 , wherein\n during the exposure operation, as the second stage is moved, another head is used instead of one head of three of the heads that face the grating section, and the positional information of the second stage is measured by three heads including two remaining heads and the another head, instead of the three heads used previously, the another head being different from the three heads used previously, and the two remaining heads excluding the one head of the three heads used previously.
