| 摘要 | An immersion lithographic projection apparatus is disclosed in which liquid is provided between a projection system of the apparatus and a substrate. The use of both liquidphobic and liquidphilic layers on various elements of the apparatus is provided to help prevent formation of bubbles in the liquid and to help reduce residue on the elements after being in contact with the liquid. | ||

| 主权项 | 1. A lithographic apparatus, comprising: a substrate table constructed to hold a substrate; a projection system configured to project a patterned radiation beam onto a target portion of the substrate; and a liquid supply system configured to provide an immersion liquid to a space below a final element of the projection system and above a surface comprising a top surface of the substrate and/or of the substrate table, wherein at least part of a downwardly facing planar surface of the liquid supply system is liquidphilic with respect to the immersion liquid. | ||
