  • Patent number: 7911026
    Abstract: Carrier including: a substrate having a first interface with first contact holes, and a second interface, which lies opposite the first interface, with second contact holes. The substrate includes a substrate body and electrically conductive contact channels formed therein, wherein each of the contact channels electrically conductively connects a first contact hole to a second contact hole. The carrier also includes a front-side wiring layer arranged on the first interface and; has a first front-side metallization layer formed therein such that it includes a first capacitor electrode for electrically connecting microelectronic devices and/or circuits to a first pole of a signal or supply voltage.

  • Patent number: 7868452
    Abstract: The invention relates to an ultrathin semiconductor circuit having contact bumps and to a corresponding production method. The semiconductor circuit includes a bump supporting layer having a supporting layer thickness and having a supporting layer opening for uncovering a contact layer element being formed on the surface of a semiconductor circuit. An electrode layer is situated on the surface of the contact layer element within the opening of the bump supporting layer, on which electrode layer is formed a bump metallization for realizing the contact bump. On account of the bump supporting layer, a thickness of the semiconductor circuit can be thinned to well below 300 micrometers, with the wafer reliably being prevented from breaking. Furthermore, the moisture barrier properties of the semiconductor circuit are thereby improved.

  • Patent number: 7757390
    Abstract: A bonding head includes a pressure plate to press a component (e.g., a semiconductor chip) onto a substrate. The pressure plate includes a holding surface configured to hold the component and to allow the component to be pressed uniformly onto the substrate, thus allowing a particularly reliable connection. The bonding head can further include an apparatus configured to vary the curvature of the holding surface of the pressure plate.

  • Patent number: 7674689
    Abstract: A method of making an integrated circuit includes providing a semiconductor wafer having a first surface and a second surface opposite the first surface, at least one of the first surface and the second surface including a metallization layer deposited onto the surface. The method additionally includes forming a first trench in the semiconductor wafer extending from one of the first surface and the second surface toward an other of the first surface and the second surface. The method further includes sawing a second trench in the other surface until the second trench communicates with the first trench, thus singulating the integrated circuit from the semiconductor wafer.
