Abstract

A lithographic apparatus is described having a liquid supply system configured to at least partly fill a space between a projection system of the lithographic apparatus and a substrate with liquid, a substrate temperature control system configured to provide a control signal to control a substrate temperature conditioning system based on a determined temperature; and a parameter control system configured to adjust a lithographic apparatus parameter, that is other than, or in addition to, the control signal, based on temperature information of the substrate and/or substrate table or on a measure derived from the temperature information.
