A liquid supply system provides liquid flow between the projection optical system and the substrate. In addition, a plurality of nozzles are arranged so as to provide a substantially uniform velocity distribution of the liquid flow between the substrate and the projection optical system.
CROSS-REFERENCE This is a Division of application Ser. No. 11/287,317 filed Nov. 28, 2005 (which has now matured into U.S. Pat. No. 7,483,117), which in turn is a Continuation of International Application No. PCT/JP2004/007569 filed on May 26, 2004 and that claims the conventional priority of Japanese patent Application No. 2003-151369 filed on May 28, 2003. The disclosures of these applications are herein incorporated by reference in their entireties.
According to the present invention, even when any temperature distribution appears in the liquid as a result of the occurrence of any distribution in the exposure light beam which comes into the liquid disposed between the projection optical system and the substrate, the exposure condition, for example, the projection state of the image of the pattern is adjusted depending on the distribution of the exposure light beam. Accordingly, the pattern can be transferred onto the substrate in a desired state. In this specification, the phrase �adjustment of the projection state of the image of the pattern� refers to not only the adjustment of the position of the image plane of the image of the pattern but also the adjustment of the state of the image of the pattern represented by the image formation characteristic such as the magnification and/or the distortion of the image of the pattern. The adjustment includes various types of adjustment in order to adjust the projection state of the image of the pattern. The adjustment includes not only the adjustment of the positional relationship between the image plane of the image of the pattern and the exposure surface of the substrate and/or the adjustment of the projection optical system, but also the adjustment of the wavelength of the exposure light beam, the adjustment (for example, the positional adjustment and the temperature adjustment) and/or the exchange of the optical member disposed in the optical path for the exposure light beam, the adjustment of the position of the mask, and the adjustment or regulation of the atmosphere of the optical path arriving at the substrate, including, for example, the temperature, the pressure, and the gas concentration. Therefore, the adjustment also includes the change or the regulation of the temperature, the flow rate, and the component of the liquid to be supplied to the space between the substrate and the projection optical system.
In this embodiment, the projection optical system PL is based on the reduction system having the projection magnification β which is, for example, � or ⅕. The projection optical system PL may be based on any one of the 1� magnification system and the magnifying system. The optical element 2, which is disposed at the end portion of the projection optical system PL of this embodiment, is provided detachably (exchangeably) with respect to the barrel PK. The optical element 2, which is disposed at the end portion, is exposed from the barrel PK. The liquid 1 in the liquid immersion area AR2 makes contact with only the optical element 2. Accordingly, the barrel PK formed of metal can be prevented from any corrosion or the like.
