摘要：
Liquid is supplied to a space between the projection system of a lithographic apparatus and a substrate. A flow of gas towards a vacuum inlet prevents the humid gas from escaping to other parts of the lithographic apparatus. This may help to protect intricate parts of the lithographic apparatus from being damaged by the presence of humid gas.
