摘要: A lithographic projection apparatus is disclosed. The apparatus includes a radiation system for providing a beam of radiation, a first support structure for supporting a patterning device, a second support structure for supporting a substrate, and a projection system. At least one of the first and second support structures includes a planar base, a movable stage that can be moved over the planar base, and an actuator for moving the stage. The apparatus also includes a contactless position measuring device for measuring a position of the stage, and a first pump for generating a conditioned gas flow in a volume between the measuring device and the stage. The base includes a plurality of gas channels that provide a path for the conditioned gas to flow through the base.
