    摘要: The specification describes an IC test apparatus having a test bed with sockets adapted to engage arrays of I/O solder balls/bumps on the IC chip. In one embodiment the sockets are provided with through holes to interconnect the solder bumps to the next board level with minimum electrical path length thereby reducing parasitic capacitive coupling. In another embodiment the sockets in the test bed are formed by intersecting V-grooves. If pairs of intersecting V-grooves are used, pyramid shaped features are produced at the bottom of each socket. Both the sharp edges formed by the intersecting V-grooves and the pyramid provide contact enhancement between the solder bumps and the test bed. The test bed can be made as a universal blank for a given solder bump pitch. The desired test circuit is formed at the next board level.

    摘要: The specification describes interconnection assemblies for silicon-on-silicon multichip modules. The silicon-on-silicon MCMs are mounted on epoxy/glass laminates which have a coefficient of thermal expansion (CTE) that essentially matches the CTE of silicon. In the preferred embodiment the assembly is a PC card with card edge connectors, i.e. without fixed solder interlevel interconnections, so that the CTE of the epoxy laminate comprising the card can be modified without regard to potential mismatch with a mother board.

    摘要: The specification describes an integrated passive device (IPD) that is formed on a polysilicon substrate. A method for making the IPD is disclosed wherein the polysilicon substrate is produced starting with a single crystal handle wafer, depositing a thick substrate layer of polysilicon on one or both sides of the starting wafer, forming the IPD on one of the polysilicon substrate layers, and removing the handle wafer. In a preferred embodiment the single crystal silicon handle wafer is a silicon wafer rejected from a single crystal silicon wafer production line.

    摘要: A flexible membrane test apparatus and test method for high-speed IC chips. The method and apparatus rely on locating the reference components of the test circuit very close to the contact pads of the IC chip under test. This is achieved in one embodiment by locating those components adjacent to the flexible membrane. In another embodiment, the reference components may be attached to the membrane itself, so the length of the runners connecting the contact points of the tester and the critical reference components is optimally reduced. In yet a further embodiment, the entire test circuit, in the form of an IC test chip, is located on the membrane.
