    摘要： A probe card for testing semiconductor wafers, and a method and system for testing wafers using the probe card are provided. The probe card is configured for use with a conventional testing apparatus, such as a wafer probe handler, in electrical communication with test circuitry. The probe card includes an interconnect substrate having contact members for establishing electrical communication with contact locations on the wafer. The probe card also includes a membrane for physically and electrically connecting the interconnect substrate to the testing apparatus, and a compressible member for cushioning the pressure exerted on the interconnect substrate by the testing apparatus. The interconnect substrate can be formed of silicon with raised contact members having penetrating projections. Alternately the contact members can be formed as indentations for testing bumped wafers. The membrane can be similar to multi layered TAB tape including metal foil conductors attached to a flexible, electrically-insulating, elastomeric tape. The probe card can be configured to contact all of the dice on the wafer at the same time, so that test signals can be electronically applied to selected dice as required.

    摘要： A semiconductor carrier and system for testing bumped semiconductor components, such as dice and packages, having contact bumps are provided. The carrier includes a base, an interconnect, and a force applying mechanism. The interconnect includes patterns of contact members adapted to electrically contact the contact bumps. The interconnect can include a substrate having contact members formed as recesses, or as projections, covered with conductive layers. Alternately, the interconnect can be a multi layered tape bonded directly to a base of the carrier. In addition to providing electrical connections, the contact members perform an alignment function by self centering the contact bumps within the contact members. The carrier can also include an alignment member configured to align the components with the interconnect. The system can include the carrier, a socket, and a testing apparatus such as a burn-in board in electrical communication with test circuitry.

    摘要： A method and carrier for testing semiconductor dice such as bare dice or chip scale packages are provided. The carrier includes a base for retaining a single die, an interconnect for establishing temporary electrical communication with the die, and a force applying mechanism for biasing the die and interconnect together. In an illustrative embodiment the base includes conductors arranged in a universal pattern adapted to electrically connect to different sized interconnects. Interconnects are thus interchangeable on a base for testing different types of dice using the same base. The conductors on the base can be formed on a planar active surface of the base or on a stepped active surface having different sized cavities for mounting different sized interconnects. In an alternate embodiment the carrier includes an interposer. In a first interposer embodiment, the interposer connects directly to external test circuitry and can be changed to accommodate different sized interconnects. In a second interposer embodiment, the interposer connects to conductors on the base and adapts the base for use with different sized interconnects.

    摘要： A method, apparatus and system for testing semiconductor wafers are provided. The method includes providing a wafer carrier to provide an electrical path for receiving and transmitting test signals to the wafer. The wafer carrier includes a base for retaining the wafer, and an interconnect having contact members configured to establish electrical communication with contact locations on the wafer. The wafer carrier can include one or more compressible spring members configured to bias the wafer and interconnect together in the assembled carrier. The wafer carrier can be assembled, with the wafer in alignment with the interconnect, using optical alignment techniques, and an assembly tool similar to aligner bonder tools used for flip chip bonding semiconductor dice. A system for use with the carrier can include a testing apparatus configured to apply test signals through the carrier to the wafer while the wafer is subjected to temperature cycling.

    摘要： An interconnect and system for establishing temporary electrical communication with semiconductor components having contact bumps are provided. The interconnect includes a substrate with patterns of contact members adapted to electrically contact the contact bumps. The substrate can be formed of a material such as ceramic, silicon, FR-4, or photo-chemically machineable glass. The contact members can be formed as recesses covered with conductive layers in electrical communication with conductors and terminal contacts on the substrate. Alternately, the contact members can be formed as projections adapted to penetrate the contact bumps, as microbumps with a rough textured surface, or as a deposited layer formed with recesses. The interconnect can be employed in a wafer level test system for testing dice contained on a wafer, or in a die level test system for testing bare bumped dice or bumped chip scale packages.
