  • Publication number: 20170294291
    Abstract: An electron-beam induced plasma is utilized to establish a non-mechanical, electrical contact to a device of interest. This plasma source may be referred to as atmospheric plasma source and may be configured to provide a plasma column of very fine diameter and controllable characteristics. The plasma column traverses the atmospheric space between the plasma source into the atmosphere and the device of interest and acts as an electrical path to the device of interest in such a way that a characteristic electrical signal can be collected from the device. Additionally, by controlling the gases flowing into the plasma column the probe may be used for surface modification, etching and deposition.

  • Publication number: 20140266244
    Abstract: Described are techniques for maintaining reliable and reproducible conditions for panel inspection, i.e. pixel and line defect detection, while at the same time preventing large-scale panel damage. One implementation involves an apparatus for identifying a defect in an electronic circuit incorporating a circuit driving module configured to apply an electrical test signal to the electronic circuit; a defect detection module configured to identify the defect in the electronic circuit based at least on the applied electrical test signal; a signal monitoring module configured to measure the electrical test signal at the electronic circuit; and a control module operatively coupled to the signal monitoring module and the circuit driving module and configured to control at least the circuit driving module based on the electrical test signal measured at the electronic circuit.

  • Patent number: 7973546
    Abstract: A method for testing a plurality of electronic devices formed on a large area substrate is described. In one embodiment, the method includes transferring a substrate on an end effector relative to a testing platform having a plurality of testing columns coupled thereto, the substrate having a plurality of electronic devices located thereon, and moving the substrate in a single directional axis relative to an optical axis of each of the plurality of testing columns, the single directional axis being substantially orthogonal to the optical axis to define a test area on the substrate, wherein the test area is configured to cover an entire length or an entire width of the substrate such that the testing columns are capable of testing the entire substrate as the substrate is moved through the test area.

  • Publication number: 20100327162
    Abstract: A method and apparatus for testing a plurality of electronic devices formed on a large area substrate is described. In one embodiment, the apparatus performs a test on the substrate in one linear axis in at least one chamber that is slightly wider than a dimension of the substrate to be tested. Clean room space and process time is minimized due to the smaller dimensions and volume of the system.

  • Patent number: 7786742
    Abstract: An apparatus and method for testing large area substrates is described. The large area substrates include patterns of displays and contact points electrically coupled to the displays on the large area substrate. The apparatus includes a prober assembly that is movable relative to the large area substrate and/or the contact points, and may be configured to test various patterns of displays and contact points on various large area substrates. The prober assembly is also configured to test fractional sections of the large area substrate positioned on a testing table, and the prober assembly may be configured for different display and contact point patterns without removing the prober assembly from the testing table.

  • Publication number: 20090321399
    Abstract: Methods and systems for improving the alignment between a previously formed feature and a subsequently formed feature are provided. An exemplary method can include laser scribing a workpiece (104, 550) having a previously formed first feature. The exemplary method includes imaging the workpiece (104, 550) with an imaging device (320, 420, 554, 640) so as to capture a plurality of positions of the first feature on the workpiece (104, 550) relative to the laser-scribing device (100). The exemplary method further includes using the captured positions to align output from the laser-scribing device (100) in order to form a second feature on the workpiece (104, 550) at a controlled distance from the first feature.
