Abstract:
The present invention provides an exposure apparatus which transfers a pattern of a reticle onto a substrate, the apparatus including a convey unit configured to convey the substrate while chucking and holding a lower surface of the substrate, and a control unit configured to control a conveyance condition of the convey unit so that a conveyance acceleration is lower when the convey unit conveys the substrate in a vertical direction with downward acceleration than when the convey unit conveys the substrate in the vertical direction with upward acceleration.
