    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for enhancing the overlay accuracy without impairing the processing capacity of a lithography apparatus significantly.SOLUTION: Alignment marks on a substrate are inspected during exposure thereof in order to optimize the exposure conditions. When the substrate 10 is scanned directly under an exposure and alignment unit 15, each part of the substrate passes under a detector unit 16 at first, and then passes under an exposure unit 17. Consequently, the information about the linear position, orientation, and expansion measured by the detector unit 16 for each part of the substrate 10 can be transmitted to the exposure unit 17, and the exposure conditions for each part of the substrate can be optimized when the substrate is exposed while passing under the exposure unit 17.

The projection and/or recess on the first and/or second flow-restricting surface is arranged to provide a flow resistance, per unit width of the first and/or second flow-restricting surface perpendicular to a flow, that is lower against a flow that is parallel to the certain direction than against a flow that is perpendicular to the certain direction. The flow-restricting surfaces may direct a gas flow onto a driver part that generates heat.

    Abstract: PROBLEM TO BE SOLVED: To provide a CSI algorithm for reconstructing grating profiles.SOLUTION: Solving a volume integral equation for current density J employs the implicit construction of a vector field Frelated to an electric field, Eand current density J by selection of continuous components of E and J, F being continuous at one or more material boundaries, so as to determine an approximate solution of J. F is represented by at least one finite Fourier series with respect to at least one direction, x, y, and the step of numerically solving the volume integral equation comprises determining a component of J by convolution of F, with a convolution operator M comprising material and geometric structure properties in both directions. J may be represented by at least one finite Fourier series with respect to both directions. The continuous components can be extracted using convolution operators, Pand PN, acting on E and J.

    Abstract: PROBLEM TO BE SOLVED: To enable accurate measurement without degrading throughput of an alignment sensor.SOLUTION: A measurement optical system comprises an illumination subsystem for illuminating a mark 202 with a radiation spot and a detecting subsystem 580 for detecting radiation diffracted by the mark. A substrate and the measurement optical system move relatively to each other at a first velocity (v) so as to scan the mark while synchronously moving the radiation spot relatively to the reference frame of the measurement optical system at a second velocity (v). The spot scans the mark at a third velocity (v) which is lower than the first velocity to allow more time for accurate position measurements to be acquired. An objective lens 524 remains fixed in relation to the reference frame while a moving optical element 562 imparts the movement of the radiation spot relative to the reference frame.

    Abstract: PROBLEM TO BE SOLVED: To provide an optical scanning mechanism which avoids or reduces additional cost and bulk to a sensor and/or inaccuracies in measurement.SOLUTION: The optical apparatus measures a position of a mark 202 on a lithographic substrate W. A measurement optical system comprises an illumination subsystem for illuminating the mark with a spot of radiation and a detecting subsystem 580 for detecting radiation diffracted by the mark. A tilting mirror 562 moves the spot of radiation relative to the reference frame of the measurement optical system synchronously with a scanning motion of the mark itself, to allow more time for accurate position measurements to be acquired. The mirror tilt axis 568 is arranged along the intersection of the mirror plane with a pupil plane P of an objective lens 524 to minimize artifacts of the scanning. The same geometrical arrangement can be used for scanning in other types of apparatus, for example a confocal microscope.

    Abstract: PROBLEM TO BE SOLVED: To provide various types of pressure regulation means for reducing a pressure gradient in a liquid supply system of a lithographic apparatus.SOLUTION: The liquid supply system has a liquid confinement structure configured to at least partially confine a liquid between a projection system and a substrate table of the lithographic apparatus. A high pressure gradient may cause particulate contamination in the liquid supply system and/or liquid confinement structure. A pressure gradient can be reduced by, for example, the use of slow switching in one or more valves, a bleed flow around or through one or more valves, diversion of liquid to a drain rather than or in addition to switching a valve off, a pressure regulator or flow restrictor to prevent shock waves, and a buffer liquid/damper to compensate for pressure fluctuation.
