    Abstract: An immersion lithography apparatus includes an optical assembly including an optical element, and configured to project a beam onto a substrate through immersion liquid, a containment member surrounding a path of the beam, a stage on which the substrate is held and moved below a bottom surface of the containment member with the substrate spaced from the bottom surface of the containment member, and a support system having an actuator to support and move the containment member. The containment member includes a first supply opening via which water as the immersion liquid is released, a recovery opening via which the immersion liquid is recovered from a gap between the containment member and the substrate and/or the stage, and a second supply opening via which the water is released to the gap, the second supply opening being provided radially inward of the recovery opening.

    Abstract: A lithographic projection apparatus includes a projection optics having a last element, by which an exposure light is projected onto an upper surface of a wafer through liquid covering a portion of the upper surface. The last element has a convex-shape incident surface, an exit surface from which the exposure light is emitted, and an outer surface arranged above the exit surface. The outer surface of the last element has a lower portion, and extends radially-outwardly and upwardly from the lower portion. The apparatus also includes a gap along the outer surface of the last element, the gap being defined between the outer surface of the last element and an opposing surface.

    Abstract: A lithographic projection apparatus includes a projection system having a last element from which an exposure light is projected onto a wafer through liquid in a space under the last element. A light incident surface of the last element has a convex shape. A liquid retaining member is disposed adjacent to a surface of the last element through which the exposure light does not pass. The liquid retaining member has an undersurface under which liquid is retained. A gap is formed between the liquid retaining member and the surface of the last element, the gap being in fluidic communication with the space. The liquid is retained between the last element and the undersurface of the liquid retaining member on one side and an upper surface of the wafer on the other side. The liquid locally covers a portion of the upper surface of the wafer.

    Abstract: Boresight and other pointing errors are detected based on a monitor beam formed by diverting a portion of a probe beam. The monitor beam is directed to a position sensitive photodetector, and the optical power received at the position sensitive photodetector is used to estimate or correct such pointing errors.

The last element has a lower surface from which the exposure light is emitted. The last element also has an outer surface which extends upwardly from an edge portion of the lower surface. The apparatus also includes a space along the outer surface of the last element, to which the liquid is supplied from above the lower surface of the last element. The space is defined by the outer surface of the last element and a surface opposing the outer surface of the last element.

    Abstract: Optical systems suitable for use as or in laser radar systems and other uses include a beam-forming unit, a beam-scan unit, and a controller. The beam-forming unit includes a first optical element, and the beam-scan unit includes a second optical element. The first optical element is movable to shape and direct a substantially collimated optical beam along a nominal propagation axis to a target, and the second optical element includes at least one movable beam deflector that moves the optical beam in a scanning manner relative to the nominal propagation axis. The controller is coupled to the beam-forming unit and beam-scan unit, and is configured to induce movement of the first optical element required for shaping and directing the optical beam along the nominal propagation axis and to induce independent motion of the beam deflector of the second optical element as required to scan the optical beam relative to the nominal propagation axis. The beam deflector can be refractive or reflective.

    Abstract: A liquid immersion lithography apparatus includes a projection system, an opening from which liquid is supplied to a space under the projection system, the opening being connectable to a liquid source via a flow passage to supply the liquid to the space and the opening being connectable to a vacuum source via the flow passage, and a holding member by which a substrate is held, the holding member being movable below the projection system and the opening. The substrate held by the holding member is exposed through the liquid that is supplied from the opening and that covers only a portion of an upper surface of the substrate.

    Abstract: A stage assembly that moves a device includes a stage that retains the device, a stage mover that moves the stage, a measurement system that provides a measurement signal that relates to the position or movement of the stage, and a control system that control the stage mover. The control system can use an estimator to estimate the position of the stage in the event the measurement signal is lost. Alternatively, the control system can be used to urge the stage against a base assembly when the measurement signal is lost to inhibit the movement of the stage.
