    摘要: Embodiments of the present invention are directed to a system and a method of controlling the flow and pressure of immersion fluid to provide stable conditions for immersion lithography. An immersion fluid is provided in a space (34) between a last optical element of an optical projection system and a workpiece during the immersion lithography process. For this purpose,a nozzle (20) is provided configured to supply immersion fluid in the gap between the last optical element and the workpiece, wherein the nozzle includes an inner cavity (34) to retain the immersion fluid in the gap and an outer cavity (53) to recover immersion fluid that exits the inner cavity.

    摘要: An immersion lithography system that compensating for any displacement of the optical caused by the immersion fluid. The system includes an optical assembly (14) to project an image defined by the reticle (12) onto the wafer (20). The optical assembly includes a final optical element (16) spaced from the wafer by a gap (24). An immersion element (22) is provided to supply an immersion fluid into the gap and to recover any immersion fluid that escapes the gap. A fluid compensation system is provided for the force on the final optical element of the optical assembly caused by pressure variations of the immersion fluid. The resulting force created by the varying pressure may cause final optical element to become displaced. The fluid compensation system is configured to provide a substantially equal, but opposite force on the optical assembly, to prevent the displacement of the final optical element.

    摘要: An apparatus and method for maintaining immersion fluid (212) in the gap adjacent the projection lens (16) during the exchange of a work piece (208) in a lithography machine (10) is disclosed. The apparatus and method includes an optical assembly (16) configured to project an image onto a work piece (208) and a stage assembly (202) including a work piece table (204) configured to support the work piece (208) adjacent the optical assembly (16). An environmental system (26) is provided to supply and remove an immersion fluid (212) from a gap between the optical assembly (16) and the work piece (208) on the stage assembly (202). After exposure of the work piece (208) is complete, an exchange system (216) removes the work piece (208) and replaces it with a second work piece. An immersion fluid containment system (214) is provided to maintain the immersion liquid (212) in the gap during removal of the first work piece (208) and replacement with the second work piece.

    摘要: A liquid recovery system is used by an immersion exposure apparatus. The liquid recovery system is provided with: a first opening (33); a gap portion (15)that is provided so that a liquid on an object that opposes the first opening can flow into the gap portion through the first opening; a liquid recovery part (40) that suctions, through a porous member, at least part of the liquid that flows into the gap portion; and a second opening (34) that is different from the first opening. The gap portion is open to the atmosphere through the second opening.
