摘要： A magnetic resonance measurement apparatus that is subject to relative motion between the apparatus and a specimen along a path includes a magnet, antennae and a circuit. The magnet polarizes the specimen, and the antennae are spatially distributed along the path. The circuit uses the antennae to perform magnetic resonance measurements and use the spatial distribution of the antennae to establish different polarization times for the magnetic resonance measurements.

摘要： A permeability estimation technique for use with spin echo signals that are received from a sample includes summing indications of the amplitudes of the spin echo signals. The results of the summing are used to determine an indication of a permeability of the sample, without using a distribution of relaxation times in the determination. The products of indications of the amplitudes of the spin echo signals may be summed, and the results of the summing may be used to determine an indication of a permeability of the sample, without using a distribution of relaxation times in the determination.

摘要： Disclosed is a method, apparatus, and program product for routing an electronic design using sidewall image transfer that is correct by construction. The layout is routed by construction to allow successful manufacturing with sidewall image transfer, since the router will not allow a routing configuration in the layout that cannot be successfully manufactured with a two-mask sidewall image transfer. A layout is produced that can be manufactured by a two-mask sidewall image transfer method. In one approach, interconnections can be in arbitrary directions. In another approach, interconnections follow grid lines in x and y-directions.

摘要： A method of measuring flare in an optical lithographic system utilizes an exposure mask with first and second discrete opaque features each having rotational symmetry of order greater than four and of different respective areas. The exposure mask is positioned in the lithographic system such that actinic radiation emitted by the lithographic system illuminates the sensitive surface of an exposure target through the exposure mask. The extent to which regions of the sensitive surface that are within the geometric image of a feature of the exposure mask are exposed to actinic radiation during due to flare is measured.

摘要： A method and system for reducing the computation time required to apply position-dependent corrections to lithography, usually mask, data is disclosed. Optical proximity or process corrections are determined for a few instances of a repeating cluster or object, usually at widely separated locations and then interpolating the corrections to the other instances of the repeating cluster based on their positions in the exposure field. Or, optical proximity corrections can be applied to the repeating cluster of objects for different values of flare intensity, or another parameter of patterning imperfection, such as by calculating the value of the flare at the location of each instance of the repeating cluster, and interpolating the optical proximity corrections to those values of flare.

摘要： A method for measuring overlay in semiconductor wafers includes a calibration phase in which a series of calibration samples are analyzed. Each calibration sample has an overlay that is known to be less than a predetermined limit. A difference spectrum for a pair of reflectively symmetric overlay targets is obtained for each calibration sample. The difference spectra are then combined to define a gross overlay indicator. In subsequent measurements of actual wafers, difference spectra are compared to the overlay indicator to detect cases of gross overlay.

摘要： An apparatus and method of compensating for lens imperfections in a projection lithography tool, includes extracting from a diffraction image created by the projection lithography tool a lens transmittance function, and then using the extracted lens transmittance function as a compensator in the lithography projection tool. Another preferred apparatus and method of synthesizing a photomask pattern includes obtaining a phase and an amplitude of a transmittance function of an imaging system; forming a computational model of patterning that includes the transmittance function of the imaging system; and then synthesizing a mask pattern from a given target pattern, by minimizing differences between the target pattern and another pattern that the computational model predicts the synthesized mask pattern will form on a wafer.
