  • Patent number: 7259452
    Abstract: A system and method for electrically and thermally coupling adjacent IC packages to one another in a stacked configuration is provided. A flex circuit is inserted in part between ICs to be stacked and provides a connective field that provides plural contact areas that connect to respective leads of the ICs. Thus, the flex does not require discrete leads which must be individually aligned with the individual leads of the constituent ICs employed in the stack. The principle may be employed to aggregate two or more contact areas for respective connection to leads of constituent ICs but is most profitably employed with a continuous connective field that provides contact areas for many leads of the ICs.

  • Patent number: 7256490
    Abstract: A test carrier for a semiconductor component includes a base for retaining the component, and an interconnect on the base having contacts configured to electrically engage component contacts on the component. The base includes conductors in electrical communication with the contacts on the interconnect, which are defined by grooves in a conductive layer. In addition, the conductors include first portions of the conductive layer configured for electrical transmission, which are separated from one another by second portions of the conductive layer configured for no electrical transmission. The test carrier is configured for mounting to a burn in board in electrical communication with a test circuitry configured to apply test signals through the contacts on the interconnect to the component.

  • Patent number: 7253516
    Abstract: Consistent with an example embodiment, an electronic device comprises an integrated circuit and a carrier substrate with a bottom and top conductive layer, and is provided with voltage supply, ground and signal transmission connections. In order to enable the use of more than one supply voltage, the integrated circuit is subdivided into core functionality and peripheral functionality, and the carrier substrate is subdivided into a corresponding core area and peripheral area. The ground connections of both core and periphery are mutually coupled through an interconnect in the carrier substrate. This interconnect is particularly a ground plane, and allows the provision of a transmission line character to the interconnects for signal transmission of the periphery.

  • Patent number: 7247938
    Abstract: The carrier (30) comprises a first etch mask (14), a first metal layer (11), an intermediate layer (12), a second metal layer (13) and a second etch mask (17). Both the first and the second etch mask (14, 17) can be provided in one step by means of electrochemical plating. After the first metal layer (11) and the intermediate layer (12) have been patterned through the first etch mask (14), an electric element (20) can be suitably attached to the carrier (30) using conductive means. In this patterning operation, the intermediate layer (12) is etched further so as to create underetching below the first metal layer (11). After the provision of an encapsulation (40), the second metal layer (13) is patterned through the second etch mask (17). In this manner, a solderable device (10) is obtained without a photolithographic step during the assembly process.
