Abstract:
1. An exposure apparatus of a scanning type which moves an object subject to exposure in a first direction parallel to a horizontal plane with a predetermined first stroke with respect to an energy beam for exposure at the time of exposure processing, the apparatus comprising: a first movable body which is movable by the predetermined first stroke at least in the first direction; a second movable body which guides movement of the first movable body in the first direction and is movable by a second stroke along with the first movable body in a second direction orthogonal to the first direction within the horizontal plane; an object holding member which holds the object and is movable in a direction at least parallel to the horizontal plane with the first movable body; a weight cancellation device which supports the object holding member from below and cancels weight of the object holding member; and a support member which extends in the first direction, and supports the weight cancellation device from below, and also is movable in the second direction by the second stroke in a state supporting the weight cancellation device from below.
