Abstract:
Position information of a movable body within an XY plane is measured with high accuracy by an encoder system whose measurement values have favorable short-term stability, without being affected by air fluctuations, and also position information of the movable body in a Z-axis direction orthogonal to the XY plane is measured with high accuracy by a surface position measuring system, without being affected by air fluctuations. In this case, since both of the encoder system and the surface position measuring system directly measure the upper surface of the movable body, simple and direct position control of the movable body can be performed.

Claim (Index 28):
The exposure method according to  claim 18 , wherein\n in the exposure operation, one head of at least three heads that face the at least three scale members, respectively, of a plurality of heads of the measurement system is switched to another head different from the at least three heads as the second stage is moved in a direction parallel to the predetermined plane, and after the switching, the positional information of the second stage is measured by at least three heads including the another head, the plurality of heads each irradiating the grating section with the measurement beam.
