Abstract: A detector detects radiation from a mask to form an image, but the focal plane of the image is in front of the mask. Any particles arranged on the mask will be in focus. However, the pattern on the mask will be out of focus. It is therefore possible to detect the existence and location of particles on a mask having an arbitrary pattern. The depth of field of the detector is small and the focal plane is no further from the surface of the patterning device than two times the depth of field.

Abstract: Movements of a lithographic apparatus include dynamic positioning errors on one or more axes which cause corresponding errors which can be measured in the applied pattern. A test method includes operating the apparatus several times while deliberately imposing a relatively large dynamic positioning error at different specific frequencies and axes. Variations in the error in the applied pattern are measured for different frequencies and amplitudes of the injected error across a frequency band of interest for a given axis or axes. Calculation using said measurements and knowledge of the frequencies injected allows analysis of dynamic positioning error variations in frequency bands correlated with each injected error frequency.

Abstract: Improved low k1 lithographic imaging is disclosed by optimizing or improving an illumination polarization condition. The polarization condition may be a pre-defined spatially varying polarization, or a spatially customized local polarization of bright illumination points based on tracking a value of a desired lithographic response. Several non-traditional polarization conditions, e.g., TM/TE polarization (with or without a central TM region), diagonal polarization, and Y+X polarization (typically for dark field illumination) are disclosed, that offer substantial imaging advantages for specific lithographic problems, especially at low k1 values. The initial polarization definition may be limited to specific fixed polarization angles.
Abstract: A substrate table positioning device that is supported by four bearing elements is provided. The substrate table positioning device also includes a balance mass. Two of the bearing elements support the base frame in such a way that they can move in a vertical direction independently of the other bearing elements. This can be achieved by using a hinge. This structure of substrate table positioning device has a higher lowest Eigen frequency of oscillation than that of substrate table positioning devices supported by three bearing elements. As such, the balance mass is not excited by typical vibrations that occur in the lithographic apparatus. This enables better positional control of the substrate table. It also enables at least some of the dimensions of the frame elements of the balance mass to be reduced.

Abstract: A method of measurement of at-resolution overlay offset may be implemented in a scatterometer. At least three targets are provided on a wafer, each target comprising a first marker grating and a second interleaved marker grating and each target having a different overlay bias between its first and second marker. The first and second markers are provided by subsequent lithography steps in a double patterning lithographic process. The targets are measured with a scatterometer and for each target a measured CD of at least one of the markers is determined using reconstruction. The CD of the first marker may be fixed in the reconstruction. The measured CDs and at least one of the overlay biases is used to determine an overlay result corresponding to a minimum measured CD. The overlay result may be determined by fitting a function such as a parabola to the measured CDs and the overlay biases and determining the overlay at the minimum of the fitted function.
