  • Patent number: 7253514
    Abstract: A connecting element for electrically connecting a semiconductor chip and a superordinate circuit board includes an elastic metal strip that is bent forming two metal limbs with flattened limb ends, thus forming a base between the metal limbs which is suitable for contacting and providing electrical connectivity to a plurality of contact pads of a superordinate circuit board. At least one of the two limb ends is electrically connected to the contact areas of a semiconductor chip, while the other limb end is elastically supported on the top side of the semiconductor chip, thereby enabling the connecting element to be self supporting.

  • Publication number: 20070158815
    Abstract: A BGA package is disclosed including a base IC structure having a base substrate, with an opening running length-wise there through. A first semiconductor chip is mounted face-down on the base substrate so the bond pads thereof are accessible through the opening. The package also includes a secondary IC structure including a secondary substrate, having an opening running there through, and a second semiconductor chip. The second chip is mounted face-down on the secondary substrate so that the bond pads thereof are accessible through the opening in the secondary substrate. An encapsulant fills the opening in the secondary substrate and forms a substantially planar surface over the underside of the secondary substrate. The substantially planar surface is mounted to the first chip of the base IC structure through an adhesive. Wires connect a conductive portion of the secondary IC structure to a conductive portion of the base IC structure.

  • Patent number: 7198979
    Abstract: A method of stacking semiconductor chips includes providing four semiconductor chips that each include a top surface with central bond pads. Each of the bond pads is electrically coupled to second bond pads located in a peripheral portion of the semiconductor chip through a conductive layer. The first and the second semiconductor chips are arranged alongside one another on a carrier substrate. The second bond pads from the first and second semiconductor chips are bonded to corresponding landing pads on the substrate. The third semiconductor chip is then stacked over the first semiconductor chip and the fourth semiconductor chip over the second semiconductor chip. The second bond pads of the third and fourth semiconductor chips can then be bonded to contact pads of the substrate. The substrate can then be separated into a first stack that includes the first and third semiconductor chips and a second stack that includes the second and fourth semiconductor chips.

  • Publication number: 20060091518
    Abstract: A semiconductor module having an internal semiconductor chip stack on a wiring substrate is disclosed. In one embodiment, the semiconductor chip stack has semiconductor chips which are arranged such that they are offset, the semiconductor chips having bonding connection pads in at least one edge region of their active top side. These bonding connection pads are electrically connected to the wiring substrate via bonding connections. In this case, the semiconductor chips are stacked on top of one another in an offset manner such that the bonding connection pads remain free of a semiconductor chip which is stacked on top of them. In this case, the semiconductor chips may be identical silicon chips which may differ, for example in pairs, in terms of their wiring structure for the centrally arranged contact areas in different edge regions.

The carrier substrate has line conductor structures and contact pads. Each of the discrete components includes centrally disposed bond pads and a metallic coating, which is electrically connected to the centrally disposed bond pads. The metallic coating is disposed on an active surface area of each discrete component. A protective structure overlies a central region of the discrete component. In the preferred embodiment, the metallic coatings of each discrete component are identical. Preferably, the discrete components are stacked on the carrier substrate so as to have the same orientation, so that the protective structure serves as a spacer between the discrete components. Further, the metallic coating is electrically coupled to the carrier substrate.
