摘要: The specification describes a high density IC BGA package in which one or more IC chips are wire bonded to a BGA substrate in a conventional fashion and the BGA substrate is solder ball bonded to a printed wiring board. The standoff between the BGA substrate and the printed wiring board to which it is attached provides a BGA gap which, according to the invention, accommodates one or more IC chips flip-chip bonded to the underside of the BGA substrate. The recognition that state of the art IC chips, especially chips that are thinned, can easily fit into the BGA gap makes practical this efficient use of the BGA gap. The approach of the invention also marries wire bond technology with high packing density flip-chip assembly to produce a low cost, high reliability, state of the art IC package.

摘要: The specification describes a MCM IC package with improved RF grounding. The package has at least one RF IC chip bonded to an interconnect substrate and the substrate is interconnected to an intermediate printed wiring board (IPWB). The IPWB is interconnected in turn to a system printed wiring board (SPWB). The RF IC chip is metallized on the backside, and is flip chip bonded directly to the SPWB thereby eliminating two intermediate interconnections and reducing the impedance of the interconnection between the RF chip and the SWBP.

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.

摘要: The specification describes methods for manufacturing thin tiles for IC packages using thinning techniques. The method includes the step of thinning the IC devices in chip form. This is achieved at the final stage of assembly where the chips are flip-chip bonded to the substrate and the backside of the chips is exposed for thinning. Using this approach, final chip thickness of the order of 2-8 mils can be produced and overall package thickness is dramatically reduced.
