Abstract: A route for a substrate support that supports a substrate in an immersion lithographic apparatus is calculated to satisfy the following constraints: after the edge of the substrate first contacts the immersion space, the substrate remains in contact with the immersion space until all target portions are exposed; exposures of target portions are performed while the substrate moves in a scan direction; and all movements of the substrate between exposures are, in a plane parallel to its upper surface, either curved or only in one of the scan directions or transverse directions. In order to reduce exposure defects at the edge of the substrate the outside portion of the substrate is avoided from being exposed to the immersion liquid. The transfer routes are designed to overly the substrate surface.
