Abstract:
In an immersion lithography apparatus in which immersion liquid is supplied to a localized space, the space is substantially polygonal in plan substantially parallel to the substrate. In an embodiment, two corners of the space have a radius of curvature no greater than the width of a transition zone between the space configured to contain liquid and a surrounding configured not to contain liquid.

Claim (Index 7):
A lithographic projection apparatus, comprising:\n a support constructed to hold a patterning device, the patterning device configured to impart a radiation beam with a pattern in its cross-section to form a patterned radiation beam; a substrate table constructed to hold a substrate; a projection system configured to project the patterned radiation beam onto a target portion of the substrate; and a liquid supply system configured to at least partly fill a space between the projection system and the substrate with a liquid, the liquid supply system comprising a liquid confinement structure configured to at least partly confine the liquid within the space, an inner periphery of the liquid confinement structure adjacent the liquid substantially forming a polygon.
