Patent number: 7652491Abstract: A probe support for holding probes which serve for electrical contacting of test substrates in a prober for testing purposes comprises a probe card holder, a probe card, and a probe card adapter, The probe card and probe card adapter are electrically connected to one another as well as to a shield of electrically conductive material and are disposed such that the probe card lies in a passageway of a shield. The shield is disposed between the test substrates and the probe card holder and is electrically insulated from the holder. For testing test substrates their positioning with respect to the probes held in this manner is done by angular alignment of the contact surfaces of the test substrates to the sensor tips and the movement of the test substrates along a path which starts from a first reference position and is composed up to the first, and each additional, contact position of an x-component and a y-component.Type: GrantFiled: November 15, 2007Date of Patent: January 26, 2010Assignee: SUSS MicroTec Test Systems GmbHInventors: Stojan Kanev, Hans-Jurgen Fleischer, Stefan Kreissig, Karsten Stoll, Axel Schmidt, Andreas Kittlaus

Patent number: 7265536Abstract: 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.Type: GrantFiled: March 1, 2006Date of Patent: September 4, 2007Assignee: Suss Microtec Test Systems GmbHInventors: Joerg Kiesewetter, Axel Schmidt, Stefan Kreissig, Karsten Stoll, Ralph Juettner, Hans-Juergen Fleischer
