    摘要： A test carrier and an interconnect for testing semiconductor components, such as bare dice and chip scale packages, are provided. The carrier includes a base on which the interconnect is mounted, and a force applying mechanism for biasing the component against the interconnect. The interconnect includes interconnect contacts configured to make temporary electrical connections with component contacts (e.g., bond pads, solder balls). The interconnect also includes support members configured to physically contact the component, to prevent flexure of the component due to pressure exerted by the force applying mechanism. The support members can be formed integrally with the interconnect using an etching process. In addition, the support members can include an elastomeric layer to provide cushioning and to accommodate Z-direction dimensional variations.

    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.

    摘要： A semiconductor carrier for testing semiconductor components, such as bare dice and chip scale packages, and a method for fabricating the carrier are provided. The carrier includes a molded plastic base, a lead frame, and an interconnect. The interconnect includes contacts for making temporary electrical connections with corresponding contacts (e.g., bond pads, solder balls) on the components. The carrier is fabricated by attaching the interconnect to the lead frame, and then molding the plastic base to the interconnect and lead frame. An alternate embodiment carrier includes a board to which multiple interconnects are molded or laminated. In addition, clip members retain the components on the board in electrical communication with the interconnects. A gasket may be used to protect the interconnect contacts during the molding step.
