Abstract:
A multi-beam metrology system includes an illumination source configured to generate a beam array, an illumination sub-system to direct the beam array to a sample at an array of measurement locations, an imaging sub-system to image the array of measurement locations as an array of imaged spots in a detection plane, and a detection assembly to generate detection signal channels associated with each of the imaged spots. The detection assembly includes an array of detection elements configured to receive the imaged spots with separate detection elements, and one or more position detectors to measure positions of the imaged spots in the detection plane. The detection assembly further generates feedback signals for the imaging sub-system based on the measured positions of the imaged spots to adjust the positions of one or more of the imaged spots in the detection plane to maintain alignment of the array of detection elements.

Claim (Index 1):
A multi-beam metrology system, comprising:\n an illumination source configured to generate a beam array; an illumination sub-system including one or more focusing elements configured to direct the beam array to a sample at an array of measurement locations; an imaging sub-system configured to image the array of measurement locations as an array of imaged spots in a detection plane, the imaging sub-system including at least one of an adjustable lens, an adjustable deflector, or an adjustable stigmator, the one or more adjustable beam control elements configured to adjust positions of one or more of the imaged spots in the detection plane; and a detection assembly configured to generate detection signal channels associated with at least some of the imaged spots, the detection assembly comprising:\n an array of detection elements configured to receive the imaged spots with separate detection elements; and \n one or more position detectors configured to measure positions of the imaged spots in the detection plane, wherein the detection assembly generates feedback signals indicative of alignment of the imaged spots on the array of detection elements based on the positions of the imaged spots in the detection plane, wherein the imaging sub-system adjusts the positions of one or more of the imaged spots in the detection plane based on the feedback signals to maintain alignment of the imaged spots on the array of detection elements.
