摘要： A calibration target for calibrating semiconductor wafer test systems including probe testers and probe card analyzers is provided. Also provided are calibration methods using the calibration target, and a method for fabricating the calibration target. The calibration target includes a substrate with various three dimensional alignment features formed thereon. A first type of alignment feature includes a contrast layer and an alignment fiducial formed on a tip portion thereof. The contrast layer and alignment fiducial are configured for viewing by a viewing device of the probe card analyzer, or the test system, to achieve X-direction and Y-direction calibration. A second type of alignment feature includes a conductive layer formed on a tip portion thereof, which is configured to electrically engage a contact on a check plate of the probe card analyzer, or a probe contact on a probe card of the test system, to achieve Z-direction calibration. The alignment features can be formed by forming raised members on a silicon substrate, and depositing and etching metal layers on the raised members.

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 package includes a substrate having one or more dice mounted thereto, and a cover adapted to protect and form a sealed space for the dice. The cover can be pre-fabricated of molded plastic, or stamped metal, and attached to the substrate using a cured seal. A hole can also be provided through the substrate to permit pressure equalization during formation of the seal. The cover can be prefabricated in an enclosed configuration for attachment directly to the substrate, or in a planar configuration for attachment to a peripheral ridge on the substrate. In either embodiment, the cover is removable to permit defective dice to be replaced or repaired.

摘要： 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.

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.

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.
