摘要:
A method for packaging and testing a semiconductor die is provided. The method includes forming a temporary package for the die that has a size, shape and lead configuration that is the same as a conventional plastic or ceramic semiconductor package. The temporary package can be used for burn-in testing of the die using standard equipment. The die can then be removed from the package and certified as a known good die. In an illustrative embodiment the package is formed in a SOJ configuration. The package includes a base, an interconnect and a force applying mechanism. The package base can be formed of ceramic or plastic using a ceramic lamination process or a Cerdip formation process.

A through-wafer interconnect for imager, memory and other integrated circuit applications is disclosed, thereby eliminating the need for wire bonding, making devices incorporating such interconnects stackable and enabling wafer level packaging for imager devices. Further, a smaller and more reliable die package is achieved and circuit parasitics (e.g., L and R) are reduced due to the reduced signal path lengths.

An inventive method in an integrated circuit (IC) manufacturing process for using data regarding repair procedures conducted on ICs at probe to determine whether any further repairs will be conducted later in the manufacturing process includes storing the data in association with a fuse ID of each of the ICs. The ID codes of the ICs are automatically read, for example, at an opens/shorts test during the manufacturing process. The data stored in association with the ID codes of the ICs is then accessed, and additional repair procedures the ICs may undergo are selected in accordance with the accessed data. Thus, for example, the accessed data may indicate that an IC is unrepairable, so the IC can proceed directly to a scrap bin without having to be queried to determine whether it is repairable, as is necessary in traditional IC manufacturing processes.

Microelectronic imager assemblies comprising a workpiece including a substrate and a plurality of imaging dies on and/or in the substrate. The substrate includes a front side and a back side, and the imaging dies comprise imaging sensors at the front side of the substrate and external contacts operatively coupled to the image sensors. The microelectronic imager assembly further comprises optics supports superimposed relative to the imaging dies. The optics supports can be directly on the substrate or on a cover over the substrate. Individual optics supports can have (a) an opening aligned with one of the image sensors, and (b) a bearing element at a reference distance from the image sensor. The microelectronic imager assembly can further include optical devices mounted or otherwise carried by the optics supports.

An inventive method in an integrated circuit (IC) manufacturing process for using data regarding repair procedures conducted on IC's at probe to determine whether any further repairs will be conducted later in the manufacturing process includes storing the data in association with a fuse ID of each of the IC's. The ID codes of the IC's are automatically read, for example, at an opens/shorts test during the manufacturing process. The data stored in association with the ID codes of the IC's is then accessed, and additional repair procedures the IC's may undergo are selected in accordance with the accessed data. Thus, for example, the accessed data may indicate that an IC is unrepairable, so the IC can proceed directly to a scrap bin without having to be queried to determine whether it is repairable, as is necessary in traditional IC manufacturing processes.

An interconnect is provided for making electrical connections with a semiconductor die. The interconnect includes a substrate having integrally formed contact members, configured to electrically contact corresponding contact locations on the die. The interconnect also includes a pattern of conductors formed separately from the substrate, and then bonded to the substrate, in electrical communication with the contact members. The conductors can be mounted to a multi layered tape similar to TAB tape, or alternately bonded directly to the substrate. In addition, each conductor can include an opening aligned with a corresponding contact member, and filled with a conductive material, such as a conductive adhesive or solder. The conductive material electrically connects the contact members and conductors, and provides an expansion joint to allow expansion of the conductors without stressing the contact members. Also provided are a system for testing dice that includes the interconnect, and a system for testing wafers wherein the interconnect is formed as a probe card.

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 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 go second interposer embodiment, the interposer connects to conductors on the base and adapts the base for use with different sized interconnects.
