LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD

摘要

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.

主权项

1. A lithographic projection apparatus arranged to project a pattern from a patterning device onto a substrate through a liquid, the apparatus comprising a liquid confinement structure configured to confine the liquid to a space adjacent the substrate, wherein the space is smaller in plan than the substrate and is substantially polygonal in plan substantially parallel to the substrate.
