  • Publication number: 20050012917
    Abstract: A scanning projection exposure apparatus transfers a pattern of a mask onto a photosensitive substrate while moving the photosensitive substrate along a scanning direction. The scanning projection exposure apparatus can include an illumination optical system optically connected to a light source, and a projection optical system arranged in an optical path between the mask and the substrate. The illumination optical system illuminates the mask with linearly polarized light whose polarization direction extends along one of the scanning direction and a direction perpendicular to the scanning direction, without losses in quantity of light. The illumination optical system of the scanning projection exposure apparatus also can include a wave plate which is rotatable about a traveling direction of the light.

  • Publication number: 20040251428
    Abstract: Charged-particle-beam (CPB) mapping projection-optical systems and adjustment methods for such systems are disclosed that can be performed quickly and accurately. In a typical system, an irradiation beam is emitted from a source, passes through an irradiation-optical system, and enters a Wien filter (“E×B”). Upon passing through the E×B, the irradiation beam passes through an objective-optical system and is incident on an object surface. Such impingement generates an observation beam that returns through the objective-optical system and the E×B in a different direction to a detector via an imaging-optical system. An adjustment-beam source emits an adjustment beam used for adjusting and aligning the position of, e.g., the object surface and/or the Wien's condition of the E×B. The adjustment beam can be off-axis relative to the objective-optical system. For such adjusting and aligning, fiducial marks (situated, e.g.
