Abstract: A method of unloading an object from a support table, the object clamped to the support table during an exposure process by: applying a first pressure to a central region of the support table under a central portion of the object; and applying a second pressure to a peripheral region of the support table under a peripheral portion of the object, wherein during clamping the first pressure and the second pressure are controlled such that liquid is retained between the object and a seal member that is positioned radially between the central region and the peripheral region at an upper surface of the support table and protrudes towards the object, the method including: increasing the first pressure towards ambient pressure; removing at least some of the liquid retained between the object and the seal member by decreasing the second pressure; and increasing the second pressure towards the ambient pressure.

Abstract: An extraction body for a support apparatus of a lithographic apparatus. The support apparatus is configured to support an object. The extraction body is formed with an opening at a surface thereof. The opening extends within the extraction body forming a first passageway. The first passageway is configured to fluidly communicate an extraction channel in the extraction body to liquid between the surface and the object. A first pressure in the extraction channel is less than ambient pressure. At least a part of the first passageway is sized and dimensioned such that when the liquid enters the first passageway via the opening, a second pressure in the first passageway associated with surface tension of the liquid is lower than the first pressure such that at least a portion of the liquid is retained in the first passageway.

Abstract: A method of unloading an object from a support table, the object clamped to the support table during an exposure process by: applying a first pressure to a central region of the support table under a central portion of the object; and applying a second pressure to a peripheral region of the support table under a peripheral portion of the object, wherein during clamping the first pressure and the second pressure are controlled such that liquid is retained between the object and a seal member that is positioned radially between the central region and the peripheral region at an upper surface of the support table and protrudes towards the object, the method including: increasing the first pressure towards ambient pressure; removing at least some of the liquid retained between the object and the seal member by decreasing the second pressure; and increasing the second pressure towards the ambient pressure.
