Patent ID: 8120749

Claim:
A lithographic apparatus arranged to project a pattern from a patterning device onto a substrate through a liquid confined in a space adjacent the substrate and along a beam path in the space, the apparatus comprising: a liquid confinement structure configured to at least partly confine the liquid in the space, the liquid confinement structure having, a liquid confinement structure inlet to supply liquid to the space, a divider substantially parallel to a top surface of a substrate table configured to hold the substrate, to divide the space into two parts, and having an aperture to allow transmission of the pattern and liquid and an outlet to remove liquid from the space, the outlet forming a substantially closed loop around the aperture and the divider extending to a point closer to the beam path than the liquid confinement structure, and a flow channel in the divider to provide a liquid flow substantially parallel to the surface into the space, the flow channel having a flow channel inlet to the space, wherein the liquid confinement structure inlet is adjacent the divider and the flow channel inlet is closer to the beam path than the liquid confinement structure inlet.
