Abstract: A method for unloading a substrate from a support table configured to support the substrate, the method including: supplying gas to a gap between a base surface of the support table and the substrate via a plurality of gas flow openings in the support table, wherein during an initial phase of unloading the gas is supplied through at least one gas flow opening in an outer region of the support table and not through any gas flow opening in a central region of the support table radially inward of the outer region, and during a subsequent phase of unloading the gas is supplied through at least one gas flow opening in the outer region and at least one gas flow opening in the central region.

Abstract: A substrate, a substrate holder, a substrate coating apparatus, a method for coating the substrate and a method for removing the coating. A monomolecular layer is applied to the backside of the substrate or a clamp surface of the substrate holder. The friction force between the substrate backside and the substrate is small when the substrate does not experience full clamping force. After loading the substrate on the substrate holder full clamping force is exerted in order to fix the substrate. The clamping force causes local removal of the monomolecular layer, resulting in an increase of the friction force between the substrate and the substrate holder.
