  • Lithographic apparatus and device manufacturing method
    Patent number: 9482962
    Abstract: Liquid is supplied to a space between the projection system and the substrate by an inlet. In an embodiment, an overflow region removes liquid above a given level. The overflow region may be arranged above the inlet and thus the liquid may be constantly refreshed and the pressure in the liquid may remain substantially constant.

  • Lithographic apparatus and device manufacturing method
    Patent number: 9477160
    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.

  • Lithographic apparatus and device manufacturing method
    Patent number: 9477159
    Abstract: In an embodiment, a lithographic projection apparatus has an off-axis image field and a concave refractive lens as the final element of the projection system. The concave lens can be cut-away in parts not used optically to prevent bubbles from being trapped under the lens.

  • Lithographic apparatus and device manufacturing method
    Patent number: 9477153
    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.

  • LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD
    Publication number: 20160282726
    Abstract: An immersion lithography apparatus comprises a temperature controller configured to adjust a temperature of a projection system, a substrate and a liquid towards a common target temperature. Controlling the temperature of these elements and reducing temperature gradients may improve imaging consistency and general lithographic performance. Measures to control the temperature may include controlling the immersion liquid flow rate and liquid temperature, for example, via a feedback circuit.
