摘要:
A temporary package, a method, and a system for testing a semiconductor die having a backside electrode are provided. The temporary package includes a base for retaining the die; a conductive member for electrically contacting the backside electrode on the die; and terminal contacts in electrical communication with the conductive member. The package also includes a force applying mechanism for biasing the conductive member against the backside electrode. A conductive path between the conductive member and terminal contacts can be through a wire, or through the force applying mechanism. In an alternate embodiment the temporary package includes a base and terminal contacts formed in the configuration of a conventional semiconductor package. A cover for the base can include a metal, carbon filled elastomer, conductive foam, or conductive adhesive conductive member. The conductive member can be adapted to simultaneously contact the backside electrode on the die, and a mating contact on the base in electrical communication with the terminal contact. In addition, the conductive member can function as a heat sink for cooling the die during the test procedures.

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.

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 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.
