  • Patent number: 8640324
    Abstract: A method for fabricating a compliant membrane probe for communication with an integrated circuit includes installing an array of conductive structures within a flexible membrane, the conductors comprising a beam structure having a first end and a second end, with each one of the conductors further comprising a probe tip extending from the first end, the probe tip having a throat generally surrounded by material of the flexible membrane and a head at an end of the throat such that the head is disposed at an opposite side of the flexible membrane with respect to the beam structure; and configuring the second end of the beam structure so as to be supported by a first end of the beam structure of an adjacent conductor thereto.
    Type: Grant
    Filed: December 7, 2009

  • Patent number: 6720789
    Abstract: A method and system for testing wafers, and particularly a wafer test system employing probes to provide for electrical contact with a device under test (DUT) which is located on a wafer. More particularly, also provided is a method and system for implementing wafer tests where the probes first contact a simulated wafer which incorporates an array of spaced load cells to determine the optimum probe overdrive. The DUT is then tested at the optimum overdrive.
