    Abstract: A lithographic projection apparatus is equipped with a device for manipulation and routing of at least one portion of a metrology beam of radiation. The device includes a first and a second optical wedge, wherein the second optical wedge and the first optical wedge having a relative position with respect to each other. The at least one portion of the metrology beam enters the device along an incoming optical axis at a first major surface of the first optical wedge, passes through the first and second optical wedges, and exits at a second major surface of the second optical wedge. The first and second optical wedges are arranged to at least one of rotate and translate the at least one portion of the metrology beam relative to the incoming optical axis by changing the relative position of the first and the second optical wedges.

    Abstract: A lithographic apparatus includes a radiation source (SO) configured to provide radiation to an illumination system (IL), the radiation source (SO) being configured to provide radiation in a first wavelength range and in a second wavelength range, the second wavelength range being different from the first wavelength range. The first wavelength range (2) is the primary wavelength of the lithographic apparatus. The second wavelength range (3) is used for setup of the lithographic apparatus, the setup including one or more of calibration, qualification, performance test, and alignment. The second wavelength range may also be used for exposure of a further substrate.

    Abstract: A lithographic apparatus includes a liquid confinement system to confine liquid in a space between a final element of a projection system and a substrate, and a first and a second substrate stage that are configured to mutually cooperate in order to perform a joint movement for bringing the lithographic apparatus from a first configuration, in which the liquid is confined between a first substrate held by the first substrate stage and the final element, towards a second configuration, in which the liquid is confined between a second substrate held by the second substrate stage and the final element, such that during the joint movement the liquid is essentially confined within the space with respect to the final element. The apparatus also includes a position measurement system configured to at least during the joint movement measure the position of the first and second substrate stages.

    Abstract: The invention relates to a lithographic apparatus comprising a substrate table for holding a substrate, a projection system for projecting a patterned beam onto a target portion of the substrate; and a displacement measuring system configured to measure the position of said substrate table in at least three degrees of freedom. Said displacement measuring system comprises a first x-sensor configured to measure the position of the substrate table in a first direction and a first and a second y-sensor configured to measure the position of the substrate table in a second direction. Said displacement measuring system further comprises a second x-sensor, wherein said first and said second x-sensor and said first and second y-sensors are encoder type sensors configured to measure the position of each of said sensors with respect to at least one grid plate. Said displacement measuring system is configured to selectively use, depending on the position of said substrate table, three of said first and second x- sensors and said first and second y-sensors to determine the position of said substrate table in three degrees of freedom.
