Stage apparatus, fixation method, exposure apparatus, exposure method, and device-producing method
A stage apparatus including: a movement member movable with a plate member placed on a placement surface; and a fixing apparatus that fixes said plate member to said placement surface in parallel with said movement member passing through a prescribed first region.
1. A stage apparatus comprising:
a movement member movable with a plate member placed on a placement surface;
a fixing apparatus that fixes the plate member to the placement surface in parallel with the movement member passing through a prescribed first region; and
a conversion apparatus which converts movement of the movement member to motive force of the fixing apparatus by mechanical contact with a part of the movement member when the movement member passes through the first region.
2. A stage apparatus according to claim 1 , wherein
the movement member passes through the first region after moving from a second region in which the plate member is placed on the movement member, and
the fixing apparatus fixes the plate member to the placement surface in parallel with the movement member from the second region passing through the first region.
3. A stage apparatus according to claim 1 , wherein
the movement member passes through the first region during movement toward a third region in which the plate member is removed from the movement member, and
the fixing apparatus releases the fixing of the plate member in parallel with the movement member from the third region passing through the first region.
4. A stage apparatus according to claim 3 , wherein the second region and the third region are the same region.
5. A stage apparatus according to claim 3 , wherein a movement direction of the movement member when the fixing apparatus fixes the plate member and a movement direction when the fixing apparatus releases the fixing of the plate member are mutually opposing directions.
6. A stage apparatus according to claim 1 , wherein the conversion apparatus is a cam apparatus having a cam follower provided on the fixing apparatus and a cam member provided on a base part that supports the movement member.
7. A stage apparatus according to claim 6 , wherein the cam follower has a bearing that reduces friction with the cam member.
8. A stage apparatus according to claim 6 , wherein the cam member has a shock-absorber that reduces resistance when contact is made with the cam follower.
9. A stage apparatus according to claim 6 , further comprising a pull-back apparatus that causes the cam member to pull back from a movement path of the movement member.
10. A stage apparatus according to claim 2 , wherein the conversion apparatus has a cam apparatus, at least part of the cam apparatus being disposed in the second region.
11. A stage apparatus according to claim 1 , wherein the fixing apparatus has a holding apparatus that holds the fixing of the plate member.
12. A stage apparatus according to claim 1 , wherein the fixing apparatus has a resilient body in a part that makes contact with the plate member.
13. A stage apparatus according to claim 1 , further comprising a second movement member provided so as to move in a direction that is opposite from a direction of movement of the movement member in accordance with a weight ratio with the movement member, by a reaction force generated when the movement member is driven, wherein
a weight of the movement member includes at least part of a weight of the fixing apparatus.
14. An exposure apparatus comprising a mask stage that holds a mask and a substrate stage that holds a substrate, wherein a pattern formed on the mask is exposed onto the substrate, and wherein a stage apparatus according to claim 1 is used as at least one of the mask stage and the substrate stage.
15. A method for producing a device, which includes a lithography step, wherein an exposure apparatus according to claim 14 is used in the lithography step.
