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 14):
The exposure apparatus according to  claim 13 , wherein\n the correction information is acquired while four heads face the four scale members, respectively, the four heads including the three heads used before the switching and the another head.
