摘要:
A lithographic projection apparatus is disclosed. The apparatus includes a substrate support constructed to support a substrate, a projection system configured to project a patterned radiation beam onto a target portion of the substrate, and a frame onto which at least a part of the projection system is mounted. A fluid provider is arranged to provide a fluid between the substrate and a downstream end of the projection system. The apparatus also includes an actuator associated with the frame and with the fluid provider and arranged to position the fluid provider, and a cushion system for cushioning vibrational forces when the actuator positions the fluid provider.

An apparatus (AS) measures positions of marks (202) on a lithographic substrate (W). A measurement optical system comprises illumination subsystem (504) for illuminating the mark with a spot of radiation (206) and as detecting subsystem (580) for detecting radiation diffracted by the mark. The substrate and measurement optical system move relative to one another at a first velocity (vW) so as to scan the mark while synchronously moving the spot of radiation relative to the reference frame (RF) of the measurement optical system at a second velocity (vSPOT). The spot scans the mark at a third velocity (vEFF) which is lower than the first velocity to allow more time for accurate position measurements to be acquired. In one embodiment, an objective lens (524) remains fixed in relation to the reference frame while a moving optical element (562) imparts the movement of the radiation spot relative to the reference frame.

摘要:
A radiation system for generating a beam of radiation that defines an optical axis is provided. The radiation system includes a plasma produced discharge source for generating EUV radiation. The discharge source includes a pair of electrodes constructed and arranged to be provided with a voltage difference, and a system for producing a plasma between the pair of electrodes so as to provide a discharge in the plasma between the electrodes. The radiation system also includes a debris catching shield for catching debris from the electrodes. The debris catching shield is constructed and arranged to shield the electrodes from a line of sight provided in a predetermined spherical angle relative the optical axis, and to provide an aperture to a central area between the electrodes in the line of sight.
