    Abstract: A single layer ceramic capacitor for wire bonding or solder or epoxy attachment wherein a bottom metallization is of a lesser purity than a top metallization whereby the bottom metallization may be effectively soldered without leaching of the metal and the top metallization may be wire bonded. In an exemplary embodiment, the top metallization is essentially pure gold and the bottom metallization is an alloy of gold and platinum and/or palladium. The top and bottom metallizations are provided on a dielectric body that advantageously comprises a ceramic having a sintering temperature below the melting point of gold. In a further exemplary embodiment, the capacitance of the capacitor may be enhanced by providing one or more interior metallization planes parallel to the exterior metallizations and connected thereto by conductive vias.

    Abstract: An improved multi-chip module includes a main circuit board having an array of electrical interconnection pads to which are mounted a plurality of IC package units. Each IC package unit includes a pair of IC packages, both of which are mounted on opposite sides of a package carrier. The package units may be mounted on one or both sides of the main circuit board. A first primary embodiment of the invention employs a laminar package carrier having a pair of major planar surfaces. Each planar surface incorporates electrical contact pads. One IC package is surface mounted on each major planar surface, by interconnecting the leads of the package with the contact pads on the planar surface, to form the IC package unit. A second primary embodiment of the invention utilizes a carrier substrate, which has a pair of recesses for back-to-back surface mounting of the IC package pair. The two IC packages may be in contact with opposite sides of a heat sink layer embedded within the carrier substrate. Each resulting IC package unit is surface mounted to the main circuit board. A third primary embodiment of the invention incorporates features of both the first and second primary embodiments. One of the packages is mounted on a planar surface of the carrier right side up, while the other package is mounted on the carrier in a recess upside down. Several variants of this embodiment are possible. Either the IC package that is mounted on the planar surface of the carrier, or the IC package that is mounted within the recess, may be mounted adjacent to the main circuit board. In the former case, the adjacent package of the package unit fits within a recess on the main circuit board. In the latter case, the adjacent package of the package unit mounts on a planar surface of the main circuit board. For any of the three primary main embodiments, the carrier may be equipped with its own set of interconnection leads which interface with the interconnection pads on the main circuit board or connection may be made directly between the leads of one package and the interconnection pads of the circuit board.

    Abstract: An electronic assembly includes one or more conductive clamps (302, 304, FIG. 3), which are used to supply current to an integrated circuit (IC) package (308). The conductive clamps are attached to a printed circuit (PC) board (312), which supplies the current to the IC package over one clamp, and receives returned current from the IC package over another clamp. Each clamp contacts a contact pad (330) on the surface of the PC board, and contacts another contact pad (334) on the top surface of the IC package. Vias (338, 339) and conductive planes (340, 342) within the package then carry current to and from an IC (e.g., IC 306) connected to the package. In another embodiment, the clamp (904, FIG. 9) holds a conductive structure (902) in place between the PC board contact pad (908) and the IC package contact pad (914), and current is carried primarily over the conductive structure, rather than over the clamp.

    Abstract: To accommodate thermal stresses arising from different coefficients of thermal expansion (CTE) of a packaged or unpackaged die and a substrate, the package incorporates two or more different interconnect zones. A first interconnect zone, located in a central region of the die, employs a relatively stiff interconnect structure. A second interconnect zone, located near the periphery of the die, employs a relatively compliant interconnect structure. Additional interconnect zones, situated between the first and second interconnect zones and having interconnect structure with compliance qualities intermediate those of the first and second zones, can optionally be employed. In one embodiment, solder connections providing low electrical resistance are used in the first interconnect zone, and compliant connections, such as nanosprings, are used in the second interconnect zone. Methods of fabrication, as well as application of the package to an electronic assembly, an electronic system, and a data processing system are also described.
