Abstract

Official abstract text for this publication.

A liquid supply system for an immersion lithographic apparatus provides a laminar flow of immersion liquid between a final element of the projection system and a substrate. A control system minimizes the chances of overflowing and an extractor includes an array of outlets configured to minimize vibrations.

First claim

Opening claim text (preview).

The invention claimed is: 1. A lithographic apparatus, comprising: a movable table; a projection system configured to project a radiation beam onto a radiation-sensitive target portion of a substrate; and a barrier member configured to at least partly contain a liquid in a space between the projection system and the table, the barrier member comprising an outlet to remove liquid from the space, the outlet having a two-dimensional array of holes in an external surface of the ba…
