  • Patent number: 9790130
    Abstract: A method of joining a metal-ceramic substrate having metallization on at least one side to a metal body by using metal alloy is disclosed. The metal body has a thickness of less than 1.0 mm and the metal alloy contains aluminum and has a liquidus temperature of greater than 450° C. The resulting metal-ceramic module provides a strong bond between the metal body and the ceramic substrate. The resulting module is useful as a circuit carrier in electronic appliances, with the metal body preferably functioning as a cooling body.

  • Patent number: 8876996
    Abstract: The invention relates to a method for the manufacture of double-sided metallized ceramic substrates according to the direct-bonding process. The method enables a ceramic substrate to be bonded to a metal plate or foil on the upper side and the underside in only one process sequence. The composite to be bonded is located on a specially designed carrier structured on the upper side with a plurality of contact points. After the bonding process the composite of metal plates and ceramic substrate can be detached from the carrier free of any residue.

  • Publication number: 20060267185
    Abstract: The invention relates to an encapsulated power semiconductor assembly comprising a substrate consisting of an insulation material (ceramic), provided with a plurality of islands, which are composed of a thermal conductive material, in particular of partial surfaces of a metal layer. Power semiconductor chips are soldered onto said islands. Electric connections that run from the chips to the connecting elements are produced in the form of bonding pads on additional islands or in the form of wires and islands that are configured as printed conductors. The substrate and the chips are encapsulated, whereas the connection elements project beyond said encapsulation and the metallic underside of the substrate is exposed in order to be fastened to a heat sink.

  • Patent number: 7030426
    Abstract: In a power semiconductor component produced in a planar technique, a near-surface structure having at least one depression is formed in a surface region of an edge termination adjacent a main surface of the semiconductor body. The structure lies inside a space charge region formed when a voltage is applied at a junction between semiconductor regions of opposite conduction type. Dielectric material may fill the depression and form a passivation layer on the surface region. The depression may be an annular trench having a width to depth ratio ?1. Alternatively, the structure may be waffle-shaped with multiple depressions.

  • Patent number: 5699232
    Abstract: A power semiconductor module includes a plastic housing having a bottom plane in which a substrate is disposed. Disposed inside the module are the substrate, structures on the substrate, a rubber-like soft encapsulation and a hard encapsulation above the soft encapsulation. Internal struts of the housing extend into the soft encapsulation and, if appropriate, have ends with transverse extensions disposed within the soft encapsulation. The effect of this module construction is that a back pressure or reaction opposes forces acting externally on the substrate.
