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.

Claim (Index 1):
An angle-resolved reflectometer comprising:\n a coherent illumination source; a controller, wherein the controller includes one or more processing units; an optical system arranged to scan a test pattern of a sample with a spot of coherent light from the coherent illumination source, wherein the scan is configured with an adjustable scan size and density, wherein the scan is performed according to a scanning pattern, wherein the scanning pattern causes the spot to be scanned across the test pattern, wherein the optical system includes a scanning mirror configured to control a position of the spot of coherent light; a detector configured to collect light reflected from the test pattern of the sample to yield a plurality of pupil images of a light distribution in a collection pupil; and a processing unit configured to generate a composite image by combining two or more of the plurality of pupil images of the light distribution collected in the collection pupil.
