    摘要: A wafer probe station is provided with a wafer chuck, a wafer fastened on the chuck by vacuum suction, and a probe needle arrangement above the wafer to test the wafer at high frequencies by contacting selected pads on the wafer and alternately pads on a calibration substrate also fastened on the wafer chuck. A procedure for reproduction of a calibration position of an aligned and afterwards displaced calibration substrate uses first and second measurement systems to calculate a new offset position of the calibration substrate after a second wafer is loaded on the wafer chuck. In a last step, the wafer chuck is driven by a 4axis manipulator stage to the new calibration position from the recent position.
