Abstract:
Conductive connections between components of an integrated circuit package are made, wherein carbon nanotubes (130, 430) extend from a surface of a first integrated circuit package component (120, 410) and distal ends of the carbon nanotubes are embedded in a connector (422) at a second integrated circuit package component (110, 420). The embedding approach involves, e.g., physical coupling (i.e., pressing) of the carbon nanotubes and the connector together. This approach is applicable to coupling a variety of components together, such as integrated circuit dies (flip chip (120) and conventional (420) to package substrates (110, 410) and/or leadframes (410).
Abstract:
Carbon nanotube material is used in an integrated circuit substrate. According to an example embodiment, an integrated circuit arrangement (100) includes a substrate (110) with a carbon nanotube structure (120) therein. The carbon nanotube structure is arranged in one or more of a variety of manners to provide structural support and/or thermal conductivity. In some instances, the carbon nanotube structure is arranged to provide substantially all structural support for an integrated circuit arrangement. In other instances, the carbon nanotube structure is arranged to dissipate heat throughout the substrate. In still other instances, the carbon nanotube structure is arranged to remove heat from selected portions of the carbon nanotube substrate.

Abstract:
Stacked die arrangements are implemented using a variety of methods. Using one such method, a first (108) and second (104) die are bonded to a support structure (106) that substantially circumscribes an interface region (114). The interface region includes a material having a pliability that is consistent with the thermal coefficient of expansion of the dies and that is greater than the pliability of support structure (106).
Abstract:
Electrical connection in an integrated circuit arrangement is facilitated with carbon nanotubes. According to various example embodiments, a carbon nanotube material (120, 135) is associated with another material (130, 125) such as a metal. The carbon nanotube material facilitates the electrical connection between different circuit components. Exemples include bond wires, leadframes and circuit board interconnects.
Abstract:
A substrate material (130) for mounting an integrated circuit (100) contains a non-electrically-conductive mesh (135) of thermally-conductive material. Because the mesh is electrically-non-conductive, it can purposely be configured to contact any and all of the circuit traces (155) that are proximate to the substrate, thereby using the circuit traces (155) as thermally-coupled heat sinks. In a preferred embodiment, the thermally-conductive mesh (135) replaces the structural fiberglass mesh that is conventionally used in substrates, thereby allowing the mesh (135) to serve a dual structural and thermal function.
Abstract:
In enhancing signal quality through packages, meta-materials may be used. Meta-materials are designed to make the signal act in such a way as to make the shape of the signal behave as though the permittivity and permeability are different than the real permittivity and permeability of the insulator used. In an example embodiment, a substrate (10) is configured as a meta-material. The meta-material provides noise protection for a signal line (15) having a pre-determined length disposed on the meta-material. The substrate comprises a dielectric material (2, 4, 6) having a topside surface and an underside surface. A conductive material (30) is arranged into pre-determined shapes (35) having a collective length. Dielectric material envelops the conductive material and the conductive material is disposed at a first predetermined distance (55) from the topside surface and at a second predetermined distance from the underside surface. The collective length of the conductive material (30) is comparable to the pre-determined length of the signal line (15).
