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 18):
The exposure method according to  claim 17 , wherein\n positional information of the substrate is detected by a detection system provided at the metrology frame, spaced apart from the projection optical system, in the exposure operation, the second stage is moved below the scale member so that at least three of the four heads face the scale member, and in a detection operation of the substrate by the detection system, the second stage is moved below another scale member different from the scale member so that at least three of the four heads face the another scale member, and the another scale member is supported in a suspended manner by the metrology frame so that the detection system is located in an opening substantially surrounded by four sections of the another scale member that are different from the four sections of the scale member, a reflective two-dimensional grating being formed in each of the four sections of the another scale member.
