  • Patent number: 9529269
    Abstract: A field manipulator to provide high resolution control of position in the XY plane and/or focus control. The field manipulator includes a plate located between the patterning device and the substrate. Control of the XY position is provided by tilting of the plate, while control of the focus position may be provided by localized deformation of the plate. Both adjustments may be performed by one or more actuators that act upon one or more edges of the plate. In an embodiment, two substantially parallel plates are provided and focus control can be provided by changing the spacing between them. A liquid may be provided between the plates which may be temperature controlled to adjust the focus by changing the refractive index of the liquid.

  • Patent number: 9436099
    Abstract: In order to determine whether an exposure apparatus is outputting the correct dose of radiation and its projection system is focusing the radiation correctly, a test pattern is used on a mask for printing a specific marker onto a substrate. This marker is then measured by an inspection apparatus, such as a scatterometer, to determine whether there are errors in focus and dose and other related properties. The test pattern is configured such that changes in focus and dose may be easily determined by measuring the properties of a pattern that is exposed using the mask. The test pattern may be a 2D pattern where physical or geometric properties, e.g., pitch, are different in each of the two dimensions. The test pattern may also be a one-dimensional pattern made up of an array of structures in one dimension, the structures being made up of at least one substructure, the substructures reacting differently to focus and dose and giving rise to an exposed pattern from which focus and dose may be determined.
