Patent ID: 8841932

Claim:
A method for testing devices in a repeat structure on a substrate that is located within a vacuum chamber, the method comprising: adjusting a relative orientation of a plurality of test probes to correspond to a plurality of test contacts on a first device at a first test location, wherein each of the plurality of test probes is retained by a respective probe holder of a plurality of probe holders, wherein each of the plurality of probe holders includes a respective manipulator of a plurality of manipulators, and further wherein the adjusting includes adjusting the plurality of manipulators by moving a plurality of linkages, wherein each linkage of the plurality of linkages extends from a respective manipulator of the plurality of manipulators to a region outside the vacuum chamber; testing the first device with the plurality of test probes; translating the plurality of test probes to a second test location that includes a second device, wherein each of the plurality of probe holders is attached to a probe holder plate, wherein the translating includes translating the probe holder plate, and further wherein the translating includes maintaining the relative orientation of the plurality of test probes during the translating; and testing the second device with the plurality of test probes.
