Zusammenfassung:The invention discloses am immersion lithographic apparatus and a device manufacturing method. The immersion lithographic apparatus is disclosed that includes a fluid confinement system configured to confine fluid to a space between a projection system and a substrate. The fluid confinement system includes a fluid inlet to supply fluid, the fluid inlet connected to an inlet port and an outlet port. The immersion lithographic apparatus further includes a fluid supply system configured to control fluid flow through the fluid inlet by varying the flow rate of fluid provided to the inlet port and the flow rate of fluid removed from the outlet port.
