  • Publication number: 20080182362
    Abstract: An electronic dive and method of fabricating an electronic device. The method including placing a placement guide over a top surface of a module substrate, the placement guide having a guide opening, the guide opening extending from a top surface of the placement guide to a bottom surface of the placement guide; aligning the placement guide to an integrated circuit chip position on the module substrate; fixing the placement guide to the module substrate; placing an integrated circuit chip in the guide opening, sidewalls of the placement guide opening constraining electrically conductive bonding structures on bottom surface of the integrated circuit chip to self-align to an electrically conductive module substrate contact pad on the top surface of the module substrate in the integrated circuit chip position; and bonding the bonding structures to the module substrate contact pads, the bonding structures and the module substrate contact pads in direct physical and electrical contact after the bonding.

  • Publication number: 20080124835
    Abstract: A sealed microelectronic structure which provides mechanical stress endurance and includes at least two chips being electrically connected to a semiconductor structure at a plurality of locations. Each chip includes a continuous bonding material along it's perimeter and at least one support column connected to each of the chips positioned within the perimeter of each chip. Each support column extends outwardly such that when the at least two chips are positioned over one another the support columns are in mating relation to each other. A seal between the at least two chips results from the overlapping relation of the chip to one another such that the bonding material and support columns are in mating relation to each other. Thus, the seal is formed when the at least two chips are mated together, and results in a bonded chip structure.

  • Patent number: 7276787
    Abstract: A carrier structure and method for fabricating a carrier structure with through-vias each having a conductive structure with an effective coefficient of thermal expansion which is less than or closely matched to that of the substrate, and having an effective elastic modulus value which is less than or closely matches that of the substrate. The conductive structure may include concentric via fill areas having differing materials disposed concentrically therein, a core of the substrate material surrounded by an annular ring of conductive material, a core of CTE-matched non-conductive material surrounded by an annular ring of conductive material, a conductive via having an inner void with low CTE, or a full fill of a conductive composite material such as a metal-ceramic paste which has been sintered or fused.

  • Patent number: 6815813
    Abstract: A system and method are provided for thermal dissipation from a heat producing electronic device. The system includes a substrate for fabricating integrated circuits, the substrate having a first face and a second face. The second face is disposed substantially parallel to the first face having an electronic device disposed therein. A metallized crack stop is disposed in the first face surrounding the electronic device. A plurality of first metal conduits extend through the substrate from the second face thereof to the crack stop, wherein each first metal conduit is in thermal contact with the crack stop to provide a thermal drain from the electronic device to the second face.
