    Abstract: The invention relates to a sintering method for manufacturing structures by sintering. In addition, the invention relates to a sintered product, an electronic module, and new uses. In the method, a particle material containing conductive or semiconductive encapsulated nanoparticles is sintered, in order to increase its electrical conductivity, by applying a voltage over the particle material. In the method, a substrate is typically used, one surface of which is at least partly equipped with a layer containing nanoparticles. The method is based on thermal feedback between the voltage feed and the nanoparticles. The invention permits the manufacture of conductive and semiconductive structures and pieces by sintering at room temperature and at normal pressure.

  • Patent number: 7358616
    Abstract: A reciprocal design symmetry allows stacked wafers or die on wafer to use identical designs or designs that vary only by a few layers (e.g. metal interconnect layers). Flipping or rotating one die or wafer allows the stacked die to have a reciprocal orientation with respect to each other which may be used to decrease the interconnect required between the vertically stacked die and or wafers. Flipping and/or rotating may also be used to improve heat dissipation when wafer and/or die are stacked. The stacked wafers or die may then be packaged.
