    Abstract: A probe card assembly includes a printed circuit board with tester contacts for making electrical connections to a semiconductor tester. The probe card assembly also includes a probe head assembly with probes for contacting a semiconductor device under test. One or more daughter cards (432) is mounted to the printed circuit board such that they are substantially coplanar with the printed circuit board. The daughter cards (432) may contain a circuit for processing test data, including test signals to be input into the semiconductor and/or response signals generated by the semiconductor device in response to the test signals.

    Abstract: A contactor device comprising a plurality of probes disposed to contact ones of the electronic devices can be electrically connected to a source of test signals. A switch can be activated electrically connecting a connection to the source of test signals to a selected one of a first group of electrically connected ones of the probes disposed to contact a first set of a plurality of the electronic devices or a second group of electrically connected ones of the probes disposed to contact a second set of a plurality of the electronic devices.

    Abstract: Probes in a plurality of DUT probe groups can be connected in parallel to a single tester channel. In one aspect, digital potentiometers can be used to effectively switch the tester channel from a probe in one DUT probe group to a probe in another DUT probe group. In another aspect, switches in parallel with a resistor can accomplish such switching. In yet another aspect, a chip select terminal on each DUT can be used to effectively connect and disconnect internal DUT circuitry to the tester channel. Multiple DUT probe groups so connected can be used to create different patterns of DUT probe groups for testing different patterns of DUTs and thus facilitate sharing tester channels.

    Abstract: A probe for contacting and testing ICs on a semiconductor device includes a dielectric insulating material tip. The dielectric tip does not contaminate the surface being probed unlike metal probe tips. A contact scrub is further not required with signals being capacitively or inductively coupled from the probe tip to the IC. Testing can be performed during early fabrication steps of the wafer without the need for applying a metalization layer to the wafer to form bond pads. Testing can be performed by inductively coupling an AC signal to the probe tip, with coupling enhanced by including a magnetic material in the dielectric probe tip. Using an AC test signal enables testing of ICs without requiring separate power and ground connections.
