Patent number: 5414374Abstract: Method for particle beam testing of substrates for liquid crystal displays (LCD). This is directed to methods wherein, given a substrate (SUB1) for a liquid crystal display, either potentials or, respectively, currents are set in defined fashion with a particle beam (S1, S2 and S4) and/or potentials are measured by detecting secondary electrons (S5) at different switch statuses of the switch elements (T) of the substrate (SUB1). The geometrical integrity and the electrical functionability of the substrate (SUB1) are thereby tested, even though, for example, a supplementary plane electrode is not present for forming a capacitor. An important advantage of the method is that faulty substrates can be repaired or can be segregated even before further-processing and, thus, costs can be reduced.Type: GrantFiled: September 20, 1993Date of Patent: May 9, 1995Assignee: Siemens AktiengesellschaftInventors: Matthias Brunner, Reinhold Schmitt

Patent number: 4985681Abstract: For testing an interconnect network for shorts and interruptions, a point of the network to be tested is charged with a particle beam. Subsequently, a potential at least one further contact point is read with the same particle beam and an unaltered primary energy. An identification of potential occurs by documenting the secondary electrons triggered at the contact points. In order to avoid a disturbing change of potential during the measuring phase, the measuring time is only a fraction of the time for charging the network.Type: GrantFiled: December 27, 1985Date of Patent: January 15, 1991Assignee: Siemens AktiengesellschaftInventors: Matthias Brunner, Juergen Frosien, Reinhold Schmitt, Burkhard Lischke

Patent number: 4891523Abstract: A circuit includes an inversely fedback operational amplifier having a saw tooth deflection signal applied at its input, as well as a coil pair and an output for deflecting the particle beam of a scanning microscope within a scanned field as established by the coil current. A plurality of resistor elements are selected by a switch and a constant current source for feeding a direct current is provided to effect the image displacement at a connection P between the coil pair and respective one of the resistor elements. Since the direct current flows only through the coils but not through the resistor elements as a consequence of the feedback amplifier, image displacement is independent of magnification established by the respective resistor element.Type: GrantFiled: October 21, 1988Date of Patent: January 2, 1990Assignee: Siemens AktiengesellschaftInventor: Reinhold Schmitt

Patent number: 4748407Abstract: To measure high frequency signal curves at nodes and interconnections of integrated circuits and achieve a good chronological resolution in accordance with the sampling method, extremely short primary electron pulses are used. For such extremely short pulse widths obtainable with beam blanking systems, only individual statistically appearing secondary electrons are registered per pulse, these electrons generating current pulses having different amplitudes and different time behaviors at the output of an energy analyzer. It is proposed that the number of current pulses occurring at the output of the energy analyzer within a prescribed time interval be identified and the quotient, or ratio, thereof, be kept constant with the assistance of a feedback circuit for connection to the voltage of a retarding field electrode. The feedback circuit includes a pulse counter, a digital-to-analog converter, and a spectrometer drive.Type: GrantFiled: January 28, 1987Date of Patent: May 31, 1988Assignee: Siemens AktiengesellschaftInventors: Matthias Brunner, Reinhold Schmitt, Dieter Winkler
