    Abstract: A lithographic projection apparatus comprising: a radiation system for providing a projection beam of radiation; a support structure for supporting patterning means, the patterning means serving to pattern the projection beam according to a desired pattern; a substrate holder (2) for holding a substrate (1) said substrate holder (2) provided with means to provide a holding force for pressing the substrate against the substrate holder; releasing means (4) for ejecting said substrate (1) from said holder (2) against said holding force; and a projection system for projecting the patterned beam onto a target portion of the substrate. According to the invention, the lithographic projection apparatus comprises a controller (5) for controlling said releasing means (4) so as to release said substrate (1) from said holder (2) with a release force that is reduced preceding to final release.

    Abstract: A lithographic apparatus includes an illumination system for providing a beam of radiation, an article support for supporting a flat article to be placed in a beam path of the beam of radiation on the article support, a backfill gas feed arranged in the article support for feeding backfill gas to a backside of the article when supported by the article support, and a clamp for clamping the article against the article support during projection. According to one aspect of the invention, the apparatus includes a controller for controlling the clamp and/or the backfill gas feed pressure so as to release the clamp prior to reducing the backfill gas feed pressure.

    Abstract: A lithographic apparatus comprising: an illumination system for providing a projection beam of radiation; an article support (1) for supporting a flat article to be placed in a beam path of said projection beam of radiation on said article support (1), comprising a plurality of supporting protrusions (2), said plurality of protrusions (2) defining a support zone (3) for providing a flat plane of support; and a backfill gas feed comprising a backfill gas discharge zone (8) arranged in said support zone (3) for feeding backfill gas to a backside of said article when supported by said article support (1), for providing an improved thermal conduction between said article and said article support (1). According to the invention, said backfill gas discharge zone (8) substantially encloses said support zone (3).
