    摘要: A system and method for correcting alignment of a product on a tool and, more particularly, to a system and method for correcting alignment of a wafer on a chuck of a tool. The system is a tool comprising at least one contact near a circumference of the tool and a grounded contact proximate to the at least one contact. The method comprises measuring current on each branch of a circuit and calculating an angle of a wafer based on a difference in the current on each branch of the circuit.

    摘要: A method, system and computer program product for determining an Azimuth angle of an incident beam to a wafer are disclosed. A method comprises: using the incident beam to make a first set of measurements of calibration targets of a first set of grating angles that are different than one another; analyzing the first set of measurements to determine an reference grating angle which corresponds to a grating line to which the incident beam has a practically zero Azimuth angle; and determining the Azimuth angle of the incident beam to the wafer using the determined reference grating angle.

    摘要: A method, system and computer program product for determining an angle of incidence of a light beam illuminating a workpiece positioned on a stage are disclosed. A method for determining an angle of incidence of a light beam illuminating a workpiece positioned on a stage may include: positioning a calibration target on the stage with multiple different tilts; first determining an angle of incident of the light beam with respect to the calibration target with each tilt using a detector; mapping a response of the detector to a determined angle of incidence; and second determining the angle of incidence with respect to the workpiece based on a result of the mapping.
