    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 carrier for use in a chip-scale package, including a polymeric film with apertures defined therethrough. The apertures, which are alignable with corresponding bond pads of a semiconductor device, each include a quantity of conductive material extending substantially through the length thereof. The carrier may also include laterally extending conductive traces in contact with or otherwise in electrical communication with the conductive material in the apertures of the carrier. Contacts may be disposed on a backside surface of the carrier. The contacts may communicate with the conductive material disposed in the apertures of the carrier. A conductive bump, such as a solder bump, may be disposed adjacent each or any of the contacts. A chip-scale package including the carrier of the present invention is also within the scope of the present invention. Such a chip-scale package includes a semiconductor device invertedly disposed over the carrier such that bond pads of the semiconductor device substantially align with apertures formed through the carrier. Thus, the bond pads of the semiconductor device may communicate with the conductive bumps by means of the conductive material disposed in the apertures of the carrier. Methods of fabricating the carrier of the present invention and methods of fabricating chip-scale packages including the carrier are also within the scope of the present invention.

    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.
