    摘要: An apparatus for changing an intensity distribution of a light within an illumination field includes a structure configured to be positioned within the illumination field so that a first portion of the light within the illumination field impinges upon the structure, where the structure is translucent or opaque to a wavelength of the light. The apparatus also includes an actuator configured to cause a movement of a first portion of the structure so that a second portion of the light within the illumination field impinges upon the structure. The light within the illumination field is produced by a source configured so that a pupil fill of a beam of the light is uncontrolled, but the beam of the light downstream of the structure is substantially telecentric before and after the movement of the first portion of the structure. Related methods are also presented.

    摘要: The mask in a lithographic apparatus is clamped on a first side using a first clamping device and on a second side, different from the first side, using a second clamping device. The clamping forces are preferably applied using thin membranes. The first clamp clamps the substrate in directions parallel to the plane of the patterning device, perpendicular to the plane of the patterning device and rotationally. The second clamping device clamps the patterning device only in directions parallel to the plane of the substrate.

    摘要: A lithographic apparatus has a patterning support constructed to support a patterning device and a substrate support constructed to support a substrate. At least one of the patterning support and the substrate support is moved by an electromagnetic actuator. The actuator has a first part and a second part that are movable relative to each other. The first part has a coil structure, and the second part including a plurality of permanent magnets interacting with the coil structure. The second part is provided with a cooling structure arranged adjacent the permanent magnets. Cooling ducts are arranged between adjacent permanent magnets, or on a side of the permanent magnets facing the coil structure.

    摘要: A measurement unit to determine a position in a first and second dimension includes a diffraction type encoder and an interferometer. The diffraction type encoder determines by means of a diffraction on a first and a second diffraction grating the position in the first dimension of the second grating with respect to the first grating, The interferometer determines the position in the second dimension of a mirror. The measurement unit includes a combined optical unit to transfer an encoder measurement beam as well as an interferometer measurement beam. Further, the measurement unit may include a combined light source for the encoder as well as the interferometer. One of the first and second diffraction gratings may further show some degree of zero order reflection to provide the mirror of the interferometer.
