Abstract:
A metrology system includes a radiation source that generates light, an optical modulation unit, a reflector, an interferometer, and a detector. The optical modulating unit temporally separates a first polarization mode of the light from a second polarization mode of the light. The reflector directs the light towards a substrate. The interferometer interferes the diffracted light from a pattern on the substrate, or reflected light from the substrate, and produces output light from the interference. The detector receives the output light from the interferometer. The first and second polarization modes of the output light are temporally separated at the detector.

Claim (Index 1):
A metrology system, comprising:\n a radiation source configured to generate light; an optical modulator configured to temporally separate a first polarization mode of the light from a second polarization mode of the light; a reflector configured to direct the light towards a substrate; an interferometer configured to receive light that has been diffracted from a pattern on the substrate, or reflected from the substrate, and to produce output light from the interference between the diffracted or reflected light; and a detector configured to receive the output light from the interferometer, wherein the first polarization mode and the second polarization mode of the output light are temporally separated at the detector.
