    • PROBLEM TO BE SOLVED: To provide a method of preventing immersion exposure liquid from relatively deeply entering under a substrate. SOLUTION: There are provided a projection system for projecting radiation beam, to which a pattern is given, on a target portion of a substrate W; a substrate holding part WH for holding the substrate W; a discharge port 24 for reducing a pressure of a space between the substrate W and the substrate holding part WH; a liquid supply system for supplying liquid 11 to the space between the projection system and the substrate holding part WH; and a gas supply port 22 provided so as to be positioned in the vicinity of the lower surface of a substrate edge when the substrate W is held by the substrate holding part WH, wherein the gas supply port 22 supplies gas to the space between the substrate W and the substrate holding part WH so that the supplied liquid 11 does not substantially enter under the substrate W.

    • 要解决的问题:提供一种防止浸没曝光液体相对深入基底的方法。 解决方案:提供了一种投影系统,用于在衬底W的目标部分上投射有图案的辐射束; 用于保持基板W的基板保持部WH; 用于减小基板W和基板保持部WH之间的空间的压力的排出口24; 用于将液体11供应到投影系统和基板保持部分WH之间的空间的液体供应系统; 以及气体供给口22,其被设置为当基板W被基板保持部WH保持时位于基板边缘的下表面附近,其中,气体供给口22将气体供给到基板 W和基板保持部WH,使得供给的液体11基本上不进入基板W的下方。(C)2007,JPO&INPIT
