Abstract: A support table having: a base surface configured to be substantially parallel to a lower surface of a substrate, a plurality of burls each having a respective distal end and a first height above the base surface, the burls arranged to support the substrate by the respective distal ends, and a plurality of elongate raised protrusions protruding above the base surface, each elongate raised protrusion having a second height above the base surface that is less than the first height. The base surface has a plurality of regions within each of which some of the elongate raised protrusions are located. All of the elongate raised protrusions located within each region have substantially the same direction of elongation such that they are substantially parallel to each other so as to form between the elongate raised protrusions at least one gas flow path substantially parallel to the elongate raised protrusions.

Abstract: A lithographic apparatus includes a support table and a gas extraction system. The gas extraction system is configured to extract gas from a gap between the base surface of the support table and a substrate through at least one gas extraction opening when the substrate is being lowered onto the support table. The lithographic apparatus is configured such that gas is extracted from the gap at a first loading flow rate when the distance between the substrate and the support plane is greater than a threshold distance and gas is extracted from the gap at a second loading flow rate when the distance between the substrate and the support plane is less than the threshold distance, wherein the second loading flow rate is lower than the first loading flow rate.

Abstract: The present invention provides a testing substrate (W) for estimating stress in production substrates due to a substrate support, said testing substrate having a support surface (SS) divided into predefined portions, wherein the predefined portions comprise at least one first portion (1) having a first coefficient of friction being substantially uniform across the at least one first portion, and at least one second portion (2) having a second coefficient of friction being substantially uniform across the at least one second portion, wherein the second coefficient of friction is different to the first coefficient of friction. The present invention also provides a method for estimating stress in a substrate due to a substrate support and a system for making such an estimation.

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 holder, a method of manufacturing of the substrate holder and a lithographic apparatus having the substrate holder. In one arrangement, a substrate holder is for use in a lithographic apparatus. The substrate holder is configured to support a lower surface of a substrate. The substrate holder has a main body, a plurality of burls and a coating. The main body has a substrate-facing face. The plurality of burls protrudes from the substrate-facing face. Each burl has a distal end configured to engage with the substrate. The distal ends are configured for supporting the substrate. The coating is on the substrate-facing face between the burls. Between the burls the substrate-facing face has an arrangement of areas. Adjacent areas are separated by a step-change in distance below the support plane. Each step-change is greater than a thickness of the coating.

Abstract: A substrate table supports a substrate holder to which a substrate is clamped for exposure. The substrate table has a plurality of e-pins spaced apart from and distributed around the center of the substrate holder to receive, and lower, a substrate onto the substrate holder prior to exposure, and to raise a substrate off the substrate holder after exposure. Tip portions of the e-pins and the corresponding apertures in the substrate holder have a shape in plan including at least one re-entrant, e.g. a cross shape.
