Patent number: 7733108Abstract: A method for perpendicular positioning of a probe card relative to a test substrate, includes storing a separation position approached in a first positioning step as a distance between the needle tips of the probe card and the substrate, storing a contact position approached in a second positioning step until the probe card contacts the substrate, and displaying an image of the needle tips. For avoiding erroneous operation after a probe card has been changed, when imaging the needle tips, the stored contact position is imaged and is changed until presentation of this contact position corresponds to actual height of the tips appropriate for the respective probe card and this setting is then stored as a new contact position. A display device presents the needle tips and the stored contact position and is connected to a memory, a recording device and an input device which changes the contact position.Type: GrantFiled: December 8, 2008Date of Patent: June 8, 2010Assignee: SUSS Microtec Test Systems GmbHInventors: Stojan Kanev, Hans-Jurgen Fleischer, Stefan Kressig, Jorg Kiesewetter

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: 7560942Abstract: To arrange a probe needle in a reproducible manner, ensure reliable contact-connection of the probe needle and ensure that the probe needle is held securely even at high temperatures or test forces, a probe receptacle is provided for mounting a probe for testing semiconductor components. The probe has a probe needle and an essentially prismatic probe shaft. The probe receptacle comprises a base having a socket opening to receive the prismatic probe shaft, surrounded by a base wall. The base wall comprises at least two base wall segments which can be moved toward one another. A probe holder arm having such a probe receptacle, and test apparatus having at least one probe which has such a probe receptacle are also provided.Type: GrantFiled: February 13, 2007Date of Patent: July 14, 2009Assignee: SUSS MicroTec Test Systems GmbHInventors: Hans-Jurgen Fleischer, Axel Schmidt, Stojan Kanev, Axel Becker

Patent number: 7057408Abstract: A method of contacting a contact area with the tip of a contact needle (contact tip) in a prober and the arrangement of such a prober, is based on the object of ensuring reliable contacting and direct observation of the establishment of the contact between the contact tip and the contact area when contacting contact pads of small dimensions. The prober substantially includes a base frame with a movement device including a clamping fixture for receiving a semiconductor wafer and also contact needles, which are arranged opposite the free surface of the semiconductor wafer. The contacting of the contact tips initially requires a horizontal positioning of the semiconductor wafer, so that the contact area and the contact tip are one above the other and at a distance from each other, and subsequently moving vertically in the direction of the contact tip, until a contact of the contact tips with the contact area is established.Type: GrantFiled: June 29, 2004Date of Patent: June 6, 2006Assignee: SUSS MicroTec Test Systems (GmbH)Inventors: Stefan Schneidewind, Claus Dietrich, Jörg Kiesewetter, Stojan Kanev, Stefan Kreissig, Frank Fehrmann, Hans-Jürgen Fleischer
