Stage device and exposure apparatus
First Claim
1. A stage device comprising:
- a first stationary member extending in a first direction;
a second stationary member extending in the first direction and spaced apart from the first stationary member in a second direction that is perpendicular to the first direction;
a moving member that can cooperate with the first stationary member and with the second stationary member; and
a positioning device that positions the moving member at a position where the moving member can selectively cooperate with the first stationary member and with the second stationary member without the moving member physically contacting the first stationary member and the second stationary member.

Abstract
A stage device includes a first stationary member, a second stationary member, a moving member and positioning devices. The first stationary member extends in a first direction. The second stationary member extends in the first direction and is spaced apart from the first stationary member in a second direction perpendicular to the first direction. The moving member can cooperate with the first stationary member and with the second stationary member. The positioning devices selectively position the moving member into cooperation with one of the first and second stationary members without physically contacting the moving member with the first and second stationary members. In addition, a stage device provided with a moving member that can move within a two-dimensional plane having a first direction and a second direction perpendicular to the first direction includes a first stationary member and a second stationary member. The first stationary member extends in the first direction and is supported at a first position in a third direction that is perpendicular to the two-dimensional plane. The second stationary member extends in the first direction and is supported at a second position in the third direction, different from the first position. The moving member has a first part that can cooperate with the first stationary member, and a second part that can cooperate with the second stationary member. When two stages are replaced, generation of a positional shift on an object on the stages is prevented, and separate processing can be performed simultaneously with respect to objects on the stages.
