1. A stage apparatus provided with a holder having a substrate holding surface which holds a substrate, and a stage which supports and moves the holder, comprising:
a recovery device, which is disposed in the vicinity of the holder, that has a lyophilic portion, of which at least a part is lyophilic, and that recovers a liquid using the lyophilic portion.
said recovery device has a suction device that suctions the liquid guided to said lyophilic portion.
said substrate is suctioned to said holder, and suction force of said suction device is greater than suction force that suctions said substrate.
said suction device is disposed below said lyophilic portion, and said lyophilic portion has an inclined portion, which is inclined toward said suction device.
5. A stage apparatus according to claim 1, wherein
said recovery device has a first portion that is higher than said substrate holding surface.
6. A stage apparatus according to claim 1, wherein
said recovery device has a recessed portion that suctions the liquid by the capillary phenomenon.
7. A stage apparatus according to claim 6, wherein
at least a part of said recessed portion is lyophilic.
8. A stage apparatus according to claim 1, wherein
said recovery device has a surface that is substantially parallel to said substrate holding surface, and a liquid repellent portion of which at least a part is liquid repellent.
9. A stage apparatus according to claim 1, wherein
at least a part of said holder is liquid repellent.
10. A stage apparatus according to claim 1, wherein
said substrate holding surface is liquid repellent.
11. A stage apparatus according to claim 1, wherein
said lyophilic portion is disposed so that a space is formed between an outer circumferential part of said substrate and said lyophilic portion.
12. A stage apparatus according to claim 1, wherein
a portion of said holder that opposes said lyophilic portion is liquid repellent.
a stage apparatus according to claim 1.
14. An exposure method that exposes a pattern onto a substrate held by a holder, comprising the steps of:
disposing a lyophilic portion, at least a part of which is lyophilic, in the vicinity of the holder;
supplying liquid to the substrate; and
exposing the pattern.
recovering part of the liquid using said lyophilic portion.
16. An exposure method according to claim 14, wherein
a part of said holder is liquid repellent.
In addition, a recessed part 32 is circularly formed, in a plan view, at the substantially center part of the substrate table 52, and a support part 52 a is protrudingly provided to this recessed part 32 for supporting the substrate holder PH (refer to FIG. 4).
Furthermore, the substrate holder PH, which holds the substrate P, is disposed inside the recessed part 32 in a state wherein the substrate holder PH is supported by the support part 52 a, and wherein there is a gap between the substrate holder PH and the substrate table 52, as depicted in FIG. 4. Furthermore, the pressure in the gap between the substrate table 52 and the substrate holder PH is set to atmospheric pressure (open). Furthermore, the plate part 30, which has a flat surface 31 that is at a height substantially the same as the front surface of the substrate P, is provided around the substrate P.
As depicted in FIG. 5, the plate part 30 in the present embodiment comprises a rear surface 7 extending in the horizontal direction (substantially parallel to the substrate holding surface 33A) from the lower end part 4, which surves as a base end, of the inner circumferential surface 3. A plurality of slits (recessed parts) 8 is provided to the rear surface 7, wherein one end of each slit 8 is open to the space 39 formed between the side surface PB of the substrate P and the inner circumferential surface 3.
The following explanation is made referencing FIG. 7. Furthermore, in FIG. 7, constituent elements that are identical to those in the first embodiment, which is depicted in FIG. 4 and the like, are assigned the identical symbols, and the explanations thereof are omitted.
If a linear motor (refer to U.S. Pat. No. 5,623,853 and U.S. patent No. 5,528,118) is used in the substrate stage PST or the mask stage MST, then either an air levitation type, which uses an air bearing, or a magnetic levitation type, which uses Lorentz's force or reactance force, may be used. In addition, each of the stages PST, MST may be a type that moves along a guide or may be a guideless type.
