Abstract

A substrate holding member includes: a first holding portion that detachably holds a substrate to be immersion exposed; and a second holding portion that detachably holds a liquid recovery member, the liquid recovery member including an opening portion in which a liquid having flowed out from an upper surface of the substrate held on the first holding portion flows.

Claims

1. A liquid recovery member that is detachably held by a movable member capable of moving with respect to an optical path of an exposure light to be irradiated onto a substrate via a liquid and that comprises an opening portion in which a liquid having flowed out from an upper surface of the substrate flows.

2. The liquid recovery member according to claim 1 further comprising a recess-shaped liquid holding portion that is formed below the opening portion so as to be capable of holding a predetermined amount of the liquid having flowed in via the opening portion.

3. The liquid recovery member according to claim 2, wherein it is held by the movable member so that a part of the opening portion faces a bottom surface of the substrate.

4. The liquid recovery member according to claim 2, wherein it is held by the movable member so that the opening portion surrounds the substrate.

5. The liquid recovery member according to claim 1, wherein it is held by the movable member so that at least a part thereof faces a bottom surface of the substrate.

6. The liquid recovery member according to claim 1, wherein it is held by the removable member so as to surround the substrate.

7. The liquid recovery member according to claim 1, further comprising an absorption member that absorbs the liquid having flowed out from the upper surface of the substrate.

8. The liquid recovery member according to claim 7, wherein the absorption member includes a porous member.

9. The liquid recovery member according to claim 1, further comprising a support portion that supports the substrate.

10. The liquid recovery member according to claim 9, wherein at least either one of at least a part of an attachment operation thereof to the movable member and at least a part of an detachment operation thereof from the movable member is performed in a state with the substrate supported by the support portion.

11. The liquid recovery member according to claim 1, wherein the movable member includes a substrate holding member that detachably holds the substrate.

12. A substrate holding member for holding a substrate to be immersion exposed, comprising:

a first holding portion that detachably holds a substrate; and

a second holding portion that detachably holds a liquid recovery member, the liquid recovery member recovering a liquid having flowed out from an upper surface of the substrate held by the first holding portion.

13. The substrate holding member according to claim 12, wherein the liquid recovery member comprises:

an opening portion that is arranged so that the liquid from the upper surface of the substrate flows therein; and

a recess-shaped liquid holding portion that is formed below the opening portion so as to be capable of holding a predetermined amount of the liquid having flowed in via the opening portion.

14. The substrate holding member according to claim 13, wherein the second holding portion holds the liquid recovery member so that a part of the opening portion faces a bottom surface of the substrate.

15. The substrate holding member according to claim 13, wherein the second holding portion holds the liquid recovery member so that the opening portion surrounds the substrate.

16. The substrate holding member according to claim 12, wherein the second holding portion holds the liquid recovery member at a position lower than the substrate that is held by the first holding portion.

17. The substrate holding member according to claim 16, wherein the second holding portion holds the liquid recovery member so that at least a part of the liquid recovery member faces the bottom surface of the substrate that is held by the first holding portion.

18. The substrate holding member according to claim 16, wherein the second holding portion holds the liquid recovery member so that the liquid recovery member surrounds the substrate.

19. The substrate holding member according to claim 12, wherein the liquid recovery member comprises an absorption member that absorbs the liquid having flowed out from the upper surface of the substrate.

20. The substrate holding member according to claim 19, wherein the absorption member comprises a porous member.

21. The substrate holding member according to claim 12, wherein

the liquid recovery member comprises a support portion that supports the substrate, and

at least one of a carry-in operation of the substrate to the first holding portion and a carry-out operation of the substrate from the first holding portion is performed in a condition that the substrate is supported by the liquid recovery member.

22. The substrate holding member according to claim 21, wherein the substrate held on the first holding portion and the liquid recovery member held in the second holding portion are apart from each other.

23. An exposure apparatus, comprising:

the substrate holding member according to claim 12, wherein

a liquid immersion exposure for a substrate held by the substrate holding member is performed by irradiating an exposure light onto the substrate via a liquid.

24. The exposure apparatus according to claim 23, further comprising a liquid supply member that is capable of supplying the liquid from above the substrate.

25. The exposure apparatus according to claim 23, further comprising a first transfer device that is capable of transferring the liquid recovery member.

26. The exposure apparatus according to claim 25, wherein the first transfer device is capable of transferring the liquid recovery member while supporting the substrate by means of the liquid recovery member.

27. The exposure apparatus according to claim 26, wherein the first transfer device carries in the substrate together with the liquid recovery member to the substrate holding member and carries out the substrate together with the liquid recovery member from the substrate holding member.

28. The exposure apparatus according to claim 27, wherein the first transfer device transfers the liquid recovery member together with the substrate, passes the substrate from the liquid recovery member to the first holding portion of the substrate holding member, and subsequently passes the liquid recovery member to the second holding portion of the substrate holding member.

29. The exposure apparatus according to claim 27, wherein the first transfer device detaches the liquid recovery member from the second holding portion of the substrate holding member, passes the substrate from the first holding portion of the substrate holding member to the liquid recovery member, and subsequently carries out the liquid recovery member together with the substrate.

30. The exposure apparatus according to claim 26, further comprising

a second transfer device that transfers only the substrate, wherein

the second transfer device transfers the substrate to and from the first transfer device.

31. The exposure apparatus according to claim 25, further comprising

a container apparatus that is capable of containing the liquid recovery member, wherein

the first transfer device is capable of performing a carry-out operation of the liquid recovery member from the container apparatus and/or a carry-in operation of the liquid recovery member to the container apparatus.

32. A device manufacturing method, comprising:

exposing a substrate by using the exposure apparatus according to claim 23; and

developing the substrate that has been exposed.
