    Abstract: Systems and methods for discrete polarization scatterometry are provided. One embodiment relates to an optical subsystem of a scatterometer. The optical subsystem includes one or more light sources configured to produce light having different polarizations. The optical subsystem also includes a polarizing beam splitter configured to separate the light into two different light beams having orthogonal and mutually exclusive polarizations. The optical subsystem further includes one or more second optical elements configured to control which one of the two different light beams illuminates the wafer during measurements. The optical subsystem also includes a detection subsystem configured to separately detect two different scattered light beams resulting from illumination of the wafer. The two different scattered light beams have orthogonal and mutually exclusive polarizations. All optical surfaces of the optical subsystem used for the measurements are stationary during the measurements.

    Abstract: A device and methods for performing a photothermal measurement and relaxation compensation of a sample are disclosed. The device may include a probe beam source, a pump beam source, a sample, and a detector array. A method may include adjusting an intensity modulated pump beam power, adjusting a probe beam power to increase a response measurement location temperature and increase a modulated optical reflectance signal, directing the intensity modulated pump beam and the probe beam along a measurement path to a response measurement location on a sample for periodically exciting a region on the sample, detecting a reflected portion of the probe beam, and calculating an implantation dose.
