    Abstract: LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD The present invention relates to the method of reducing contamination of an immersion liquid in a lithographic apparatus when a closing surface is used to confine liquid in a liquid supply system. To avoid or reduce particulate contamination caused by the closing surface colliding with the liquid supply system, the closing surface is maintained at a distance away from the liquid supply system such that there is no collision between the closing surface and the liquid supply system, but the liquid is nonetheless confined.
