    摘要: A method of probe card partitioning for testing an integrated circuit die includes providing a first probe card partition layout having a first number of distinct sections. Each distinct section uses a distinct probe card for testing. The first probe card partition layout is repartitioned into a second probe card partition layout having a second number of distinct sections. The second number is less than the first number.

    摘要: A testing probe structure for wafer level testing semiconductor IC packaged devices under test (DUT). The structure includes a substrate, through substrate vias, a bump array formed on a first surface of the substrate for engaging a probe card, and at least one probing unit on a second surface of the substrate. The probing unit includes a conductive probe pad formed on one surface of the substrate and at least one microbump interconnected to the pad. The pads are electrically coupled to the bump array through the vias. Some embodiments include a plurality of microbumps associated with the pad which are configured to engage a mating array of microbumps on the DUT. In some embodiments, the DUT may be probed by applying test signals from a probe card through the bump and microbump arrays without direct probing of the DUT microbumps.
