  • Patent number: 10705432
    Abstract: A substrate table of an immersion lithographic apparatus is disclosed which comprises a barrier configured to collect liquid. The barrier surrounds the substrate and is spaced apart from the substrate. In this way any liquid which is spilt from the liquid supply system can be collected to reduce the risk of contamination of delicate components of the lithographic projection apparatus.

  • Publication number: 20190369502
    Abstract: An immersion lithography apparatus is disclosed in which liquid is supplied to a space between a projection system and a substrate, and a plate structure is provided to divide the space into two parts. The plate structure has an aperture to allow transmission of the projection beam, has through holes in it to reduce the damping effect of the presence of the plate and optionally has one or more inlets and outlets to provide various flows around the aperture in the plate. An embodiment of the invention may reduce the transportation of contaminants, stray light, temperature gradients, and/or the effect of bubbles on the imaging quality.

  • Patent number: 10488759
    Abstract: An immersion lithographic apparatus is provided with a liquid confinement structure which defines at least in part a space configured to contain liquid between the projection system and the substrate. In order to reduce the crossing of the edge of the substrate which is being imaged (which can lead to inclusion of bubbles in the immersion liquid), the cross-sectional area of the space in a plane parallel to the substrate is made as small as possible. The smallest theoretical size is the size of the target portion which is imaged by the projection system. In an embodiment, the shape of a final element of the projection system is also changed to have a similar size and/or shape in a cross-section parallel to the substrate to that of the target portion.

  • Patent number: 10466595
    Abstract: In a lithographic apparatus, a localized area of the substrate surface under a projection system is immersed in liquid. The height of a liquid supply system above the surface of the substrate can be varied using actuators. A control system uses feedforward or feedback control with input of the surface height of the substrate to maintain the liquid supply system at a predetermined height above the surface of the substrate.
