    • PROBLEM TO BE SOLVED: To provide a lithographic apparatus, in which a conduit can be fitted without requiring complicated work.
      SOLUTION: The lithographic apparatus includes a vacuum chamber 20 provided with a first gas evacuator GE1, and a conduit 22 in communication with a component inside the vacuum chamber 20. The apparatus also includes a conduit shield 24 inside the vacuum chamber 20. The conduit shield 24 provides a conduit path 25 for at least a part of the conduit 22, and shields the vacuum chamber 20 from the conduit path 25. The apparatus further includes a gas evacuation shield 29, extending at least between a gas passage 32 through the conduit shield 24 and a separate gas evacuation penetrating and connecting piece 30 through a wall 21 of the vacuum chamber 20. The gas evacuation shield 29 provides a gas evacuation path 28 from the conduit path 25 into an area outside the vacuum chamber 20, and shields the vacuum chamber 20 from the gas evacuation path 28.

    • PROBLEM TO BE SOLVED: To provide an aligner which can carry out stable exposure while keeping high vacuum state by preventing outgas from diffusing to a space wherein a mirror and a reticle are arranged.
      SOLUTION: In the aligner, light flux emitted from a light source is cast on a treatment object mounted on a first stage through an exposure optical system and the treatment object is exposed. The aligner has a partition for dividing into a first space wherein the first stage is arranged and a second space wherein the exposure optical system is arranged, a first control means for controlling vacuum degree of the first space, and a second control means for controlling vacuum degree of the second space.
