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 6):
The exposure apparatus according to  claim 1 , further comprising:\n an aerial image measurement device that detects a mark image of the mask or a mark image of the first stage via a slit pattern disposed on the upper surface of the second stage, the mark image being projected via the projection optical system and the liquid of the liquid immersion area, wherein the controller controls the second drive system so that the mark image is projected on the slit pattern following movement of the second and the third stages that have come close together and the scanning exposure is performed following detection of the mark image.
