    摘要: The formation of test probe structures is described. One test probe structure includes a tip portion and a handle portion spaced a distance away from the tip portion. The test probe structure also includes a body bend portion positioned between the tip portion and the handle portion, and an intermediate portion positioned between the body bend portion and the handle portion. The body bend portion may include a curved shape extending from the intermediate portion to the tip portion. The tip portion may be formed to be offset from a longitudinal axis defined by the intermediate portion. The test probe structure defines a length and includes a cross-sectional area that is different at a plurality of positions along the length. Other embodiments are described and claimed.

    摘要: An interposer is described to regulate the current in wafer test tooling. In one example, the interposer includes a first connection pad to couple to automated test equipment and a second connection pad to couple to a device under test. The interposer further includes an overcurrent limit circuit to connect the first and second connection pads and to disconnect the first and second connection pads when the current between the first and second connection pads is over a predetermined amount.

    摘要: Embodiments of the invention provide methods for forming electrical connections using liquid metals. Electrical connections that employ liquid metals are useful for testing and validation of semiconductor devices. Electrical connections are formed between the probes of a testing interface and the electronic interface of a device under test through a liquid metal region. In embodiments of the invention, liquid metal interconnects are comprised of gallium or liquid metal alloys of gallium. The use of liquid metal contacts does not require a predetermined amount of force be applied in order to reliably make an electrical connection.

    摘要: Embodiments of the invention describe forming a set of probes using semiconductor regions each including a plurality of vias. A first set of probe segments may be formed from a first set of vias on a first semiconductor region. A second set of probe segments may be formed from a second set of vias on a second semiconductor region and bonded to the first set of probe segments. At least one spring comprising a dielectric material may be formed to couple the first set of probe segments, while a set of metal tips disposed on the second set of probe segments.
