    摘要: A method for placement of a object such as a substrate or a mask on a table, said method including: a first placement step in which the object is placed on a first position on the table; a measuring step in which a displacement between the first position of the object and the required position of the object is determined; a removing step in which the object is released and removed from the table; a moving step in which the object and the table are moved relatively to each other by substantially the said displacement, in a direction substantially parallel to the surface of the table; and a second placement step in which the object is placed at the required position on the table.

    摘要: A lithographic projection apparatus is disclosed. The lithographic projection apparatus includes an illumination system to supply a projection beam of radiation, a first object table to hold a mask, a second object table provided with a support surface to support and hold a substrate at its backside surface and a projection system to image an irradiated portion of the mask onto a target portion of the substrate including a detector constructed and arranged to detect the presence of contamination on one or both of the support surface and the substrate backside surface.
