  • Publication number: 20070146678
    Abstract: A lithographic apparatus includes an illumination system to condition a radiation beam, a patterning device support to support a patterning device in a projection plane, the patterning device to pattern the radiation beam, a substrate table to hold a substrate, a projection system to project the patterned beam onto the substrate, and an exchange device to exchange an exchangeable object with an exchangeable object support that holds the exchangeable object during projection. The exchange device includes a load unit and an unload unit that each have a holding device to hold an exchangeable object. The holding devices are positioned substantially adjacent to each other and configured to hold an exchangeable object in a plane substantially parallel to the plane in which the exchangeable object is held in the exchangeable object support during projection. The exchangeable object support exchanges an exchangeable object with each of the holding devices.

  • Publication number: 20070058172
    Abstract: 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.

  • Publication number: 20070013894
    Abstract: In order to improve the productivity of a lithographic apparatus, a stage apparatus for holding two patterning devices is described. The patterning devices are arranged such that the distance between the patterns in the scanning direction corresponds to the length of the pattern in the scanning direction. By doing so, an improved exposure sequence may be performed by exposing a first die with a first pattern, skipping a second die adjacent to the first die, and exposing a third die adjacent to the second die using a second pattern.
