  • Patent number: 7776652
    Abstract: An inventive electronic device, such as a multi-chip module (MCM), a Single In-line Memory Module (SIMM), or a Dual In-line Memory Module (DIMM), includes a base, such as a printed circuit board, having a surface on which flip-chip pads and wire-bondable pads are provided. The flip-chip pads define an area on the surface of the base at least partially bounded by the wire-bondable pads. A first integrated circuit (IC) die is flip-chip bonded to the flip-chip pads, and a second IC die is back-side attached to the first IC die and then wire-bonded to the wire-bondable pads. As a result, the flip-chip mounted first IC die is stacked with the second IC die in a simple, novel manner.

  • Patent number: 7730372
    Abstract: An IC module, such as a Multi-Chip Module (MCM), includes multiple IC dice, each having a test mode enable bond pad, such as an output enable pad. A fuse incorporated into the MCM's substrate connects each die's test mode enable bond pad to one of the MCM's no-connection (N/C) pins, and a resistor incorporated into the substrate connects the test mode enable bond pads to one of the MCM's ground pins. By applying a supply voltage to the test mode enable bond pads through the N/C pin, a test mode is initiated in the dice. Once testing is complete, the fuse may be blown, and a ground voltage applied to the test mode enable bond pads through the ground pins so the resistor disables the test mode in the dice and initiates an operational mode. As a result, dice packaged in IC modules may be tested after packaging.

  • Patent number: 7723741
    Abstract: Methods of packaging microelectronic imagers and packaged microelectronic imagers. An embodiment of such a method can include providing an imager workpiece having a plurality of imager dies arranged in a die pattern and providing a cover substrate through which a desired radiation can propagate. The imager dies include image sensors and integrated circuitry coupled to the image sensors. The method further includes providing a spacer having a web that includes an adhesive and has openings arranged to be aligned with the image sensors. For example, the web can be a film having an adhesive coating, or the web itself can be a layer of adhesive. The method continues by assembling the imager workpiece with the cover substrate such that (a) the spacer is between the imager workpiece and the cover substrate, and (b) the openings are aligned with the image sensors. The attached web is not cured after the imager workpiece and the cover substrate have both been adhered to the web.

  • Patent number: 7683458
    Abstract: 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.

  • Patent number: 7561938
    Abstract: 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.

  • Patent number: 7488899
    Abstract: A compliant contact pin assembly and a contactor card system are provided. The compliant contact pin assembly includes a contact pin formed from a portion of a substrate with the contact pin compliantly held suspended within the substrate by a compliant coupling structure. The suspension within the substrate results in a compliant deflection orthogonal to the plane of the substrate. The contact pin assembly is formed by generally thinning the substrate around the contact pin location and then specifically thinning the substrate immediately around the contact pin location for forming a void. The contact pin is compliantly coupled, in one embodiment by compliant coupling material, and in another embodiment by compliantly flexible portions of the substrate.
