CROSS-REFERENCE TO RELATED APPLICATIONS This is a Divisional of U.S. patent application Ser. No. 11/398,572 filed Apr. 6, 2006, which is a Continuation of International Application No. PCT/JP2004/014855 filed Oct. 7, 2004, which claims priority to Japanese Application No. 2003-349550. The contents of each of the aforementioned applications are incorporated herein by reference in their entireties.
DISCLOSURE OF INVENTION To solve the above-described problems, the present invention adopts the following configurations that are illustrated in the embodiments and correspond to FIGS. 1-10.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram showing an embodiment of a device manufacturing system as an exposure apparatus of the present invention.
BEST MODE FOR CARRYING OUT THE INVENTION In the following, referring to the drawings, a substrate conveyance device and an exposure apparatus of the present invention will be described. FIG. 1 is a diagram showing an embodiment of a device manufacturing system provided with an exposure apparatus of the present invention and is a schematic diagram when viewed from the side; FIG. 2 is a diagram when FIG. 1 is viewed from above.
In FIGS. 1 and 2, device manufacturing system SYS is provided with exposure apparatus EX-SYS and coater-developer apparatus C/D-SYS (see FIG. 2). Exposure apparatus EX-SYS is provided with interface portion IF (see FIG. 2) that forms a connection portion thereof to coater-developer apparatus C/D-SYS, with exposure apparatus main body EX that by filling a space between projection optical system PL and substrate P with liquid LQ and by projecting a pattern formed on a mask onto substrate P via projection optical system PL and liquid LQ, exposes substrate P, with conveyance system H that conveys substrate P between interface portion IF and exposure apparatus main body EX, with liquid removal system 100 that is provided on the conveyance path of conveyance system H and removes liquid LQ adhering on the surface of substrate P, with imaging device 80 that constitutes a liquid detector which is provided on the conveyance path of conveyance system H and detects liquid LQ adhering on substrate P, and with controller CONT that controls the overall operation of exposure apparatus EX-SYS. Coater-developer apparatus C/D-SYS is provided with coater apparatus C that applies photoresist (photosensitive material) to the base material of substrate P before it experiences an exposure process and with development apparatus (processing apparatus) D that develops substrate P after it experienced an exposure process at exposure apparatus main body EX. Exposure apparatus main body EX is located within first chamber apparatus CH1 of which cleanliness is controlled. First chamber apparatus CH1 that accommodates exposure apparatus main body EX and second chamber apparatus CH2 that accommodates coater apparatus C and development apparatus D are connected to each other via interface portion IF. Note that in the following description, coater apparatus C and development apparatus D that are accommodated in second chamber apparatus CH2 will be collectively referred to as �coater-developer main body C/D� as necessary.
As shown in FIG. 1, exposure apparatus main body EX is provided with illumination optical system IL that illuminates mask M supported by mask stage MST with exposure light EL, with projection optical system PL that projects an image of a pattern of mask M illuminated with exposure light EL onto substrate P, and with substrate stage PST that supports substrate P. Further, exposure apparatus main body EX of the embodiment is a scan type exposure apparatus (the so-called scanning stepper) in which while synchronously moving mask M and substrate P in mutually different directions (opposite directions) along the scanning direction, the pattern formed on mask M is exposed onto substrate P. In the following description, it is assumed that the synchronous movement direction (the scanning direction), of mask M and substrate P is referred to as the X-axis direction in a horizontal plane, that the direction perpendicular to the X-axis direction in the horizontal plane, is referred to as the Y-axis direction (the non-scanning direction), and that the direction that is perpendicular to the X-axis direction and to the Y-axis direction and coincides with optical axis AX of projection optical system PL is referred to as the Z-axis direction. Further, it is assumed that the rotation (inclination) directions around the X-axis, the Y-axis, and the Z-axis are respectively referred to as the θX-direction, the θY-direction, and the θZ-direction. It should be noted that a �substrate� referred to herein comprehends a semiconductor wafer over which photoresist is applied and that a �mask� comprehends a reticle on which a device pattern to be reduction projected onto a substrate is formed.
