Zusammenfassung:A lithographic projection apparatus 1 having at least two substrate holders WT1, WT2 includes means for reducing effects of differences in images caused by differences between the two substrate holders. The apparatus 1 includes internal or external means for identifying a substrate and associating it with a respective one of the substrate holders. It then ensures that either the substrate is processed on the appropriate holder or that correction is applied to the imaging. In an alternate embodiment, the substrate is associated with a respective one of the substrate holders and is consistently processed using that substrate holder without further identification steps.
