    Abstract: Angle-resolved reflectometers and reflectometry methods are provided, which comprise a coherent light source, an optical system arranged to scan a test pattern using a spot of coherent light from the light source to yield realizations of the light distribution in the collected pupil, wherein the spot covers a part of the test pattern and the scanning is carried out optically or mechanically according to a scanning pattern, and a processing unit arranged to generate a composite image of the collected pupil distribution by combining the pupil images. Metrology systems and methods are provided, which reduce diffraction errors by estimating, quantitatively, a functional dependency of measurement parameters on aperture sizes and deriving, from identified diffraction components of the functional dependency which relate to the aperture sizes, correction terms for the measurement parameters with respect to the measurement conditions.

    Abstract: A multi-spot scanning technique using a spot array having a predetermined gap between spots can advantageously provide scalability to a large number of spots as well as the elimination of cross-talk between channels. The multi-spot scanning technique can select a number of spots for the spot array (1D or 2D), determine a separation between the spots to minimize crosstalk, and perform a scan on a wafer using the spot array and a full field of view (FOV). Performing the scan includes performing a plurality of scan line cycles, wherein each scan line cycle can fill in gaps left by previous scan line cycles. This 'delay and fill' scan allows large spacing between spots, thereby eliminating cross-talk at the detector plane. In one embodiment, the scan is begun and ended outside a desired scan area on the wafer to ensure full scan coverage.

    Abstract: An optical inspection system rapidly evaluates a substrate by illumination of an area of a substrate larger than a diffraction-limited spot using a coherent laser beam by breaking temporal or spatial coherence. Picosecond or femtosecond pulses from a modelocked laser source are split into a plurality of spatially separated beamlets that are temporally and/or frequency dispersed, and then focused onto a plurality of spots on the substrate. Adjacent spots, which can overlap by up to about 60-70 percent, are illuminated at different times, or at different frequencies, and do not produce mutually interfering coherence effects. Bright-field and dark-field detection schemes are used in various combinations in different embodiments of the system.

    Abstract: An optical scanner for use in conjunction with an infrared spectrometer is disclosed. The optical scanner translates a beam of radiation to a stationary spot on a traveling sheet of material so that ample integration time within the spectrometer is achieved. The beam path impinges on the traveling web and the radiation is reflected off the traveling web back through the optical scanner and recombined at an interferometer. The beam of radiation is kept stationary with respect to both the traveling sheet and the carriage which houses the spectrometer.
