Abstract:
Correction information is acquired for compensating for a measurement error of a second encoder system that occurs due to a displacement between four sections of a scale member of the second encoder system, based on measurement information of the second encoder system obtained in a fifth area in which four heads of the second encoder system that are provided on a second stage, which holds a substrate, respectively face the four sections of the scale member.

Claim (Index 3):
The exposure apparatus according to  claim 2 , wherein\n in the exposure operation, for drive control of the second stage that is moved from one area of the first, the second, the third and the fourth areas to another area different from the one area, one head of three heads used in the one area is switched to another head different from the three heads, of the four heads, and switching information for controlling drive of the second stage using the another head instead of the one head is acquired, based on the positional information obtained from the three heads used in the one area.
