    摘要: A lithographic apparatus, a device manufacturing method, and a projection element for use in a lithographic apparatus are disclosed. The lithographic apparatus has a radiation system for providing a pulsed beam of radiation, a patterning device for imparting the beam with a pattern to form a patterned radiation beam, and a projection system having a projection element for projecting the patterned beam onto a target portion of a substrate. The apparatus further comprises an actuator for moving the projection element for shifting the patterned beam that is projected onto the substrate during at least one pulse of the radiation system. This can be done to compensate for a positional error between a substrate table holding the substrate and an aerial image of the projection system. The positional error could occur due to mechanical vibrations in the frame system of the lithographic apparatus.

    摘要: A spatial light modulator used to pattern a radiation beam comprises an array of pixels disposed on a support. Each pixel has a light modulating element for modulating the radiation beam and a control circuit that positions the light modulating elements according to a desired pattern. The control circuit is disposed on the opposite side of the support than the light modulating elements. The control circuit comprises at least one of a digital to analog converter, an analog to digital converter, an optical fiber input, and a processor.
