  • Publication number: 20170338193
    Abstract: A description is given of a power semiconductor module 10 which can be transferred from a normal operating mode to an explosion-free robust short-circuit failure mode. Said power semiconductor module 10 comprises a power semiconductor 1 having metallizations 3 which form potential areas and are separated by insulations and passivations on the top side 2 of said power semiconductor. Furthermore, an electrically conductive connecting layer is provided, on which at least one metal shaped body 4 which has a low lateral electrical resistance and is significantly thicker than the connecting layer is arranged, said at least one metal shaped body being applied by sintering of the connecting layer such that said metal shaped body is cohesively connected to the respective potential area.

  • Patent number: 9287232
    Abstract: The invention relates to a method for producing a connection between a semiconductor component and semiconductor component and semiconductor module resistant to high temperatures and temperature changes by means of a temperature impinging process, wherein a metal powder suspension is applied to the areas of the semiconductor module to be connected later; the suspension layer is dried, outgassing the volatile components and generating a porous layer; the porous layer is pre-sealed without complete sintering taking place throughout the suspension layer; and, in order to obtain a solid electrically and thermally conductive connection of a semiconductor module to a connection partner from the group of: substrate, further semiconductor or interconnect device, the connection is a sintered connection generated without compression by increasing the temperature and made of a dried metal powder suspension that has undergone a first transport-safe contact with the connection partner in a pre-compression step and has bee

  • Patent number: 8802564
    Abstract: A method of manufacturing a semiconductor component includes the steps of manufacturing of a wafer, applying structures of components on the wafer to form a wafer assembly, applying a metal coating on the wafer, removing the metal coating in non-contact areas of the components, applying surrounds on the edge areas of the components, arranging the wafer on a foil held by a clamping ring, separating the components of the wafer compound carried by the foil from one another, arranging a covering mask on the areas of the separated components carried by the foil which are not to be coated, applying a metal coating on the separate components covered with the mask, removal of the mask, and removal of the components from the foil and further processing the separate components wherein that applying a metal coating on the separate components covered by the mask takes place by means of thermal spraying.

  • Patent number: 8546923
    Abstract: Method for manufacturing a rigid power module with a layer that is electrically insulating and conducts well thermally and has been deposited as a coating, the structure having sprayed-on particles that are fused to each other, of at least one material that is electrically insulating and conducts well thermally, having the following steps: manufacturing a one-piece lead frame; populating the lead frame with semiconductor devices, possible passive components, and bonding corresponding connections, inserting the thus populated lead frame into a compression mold so that accessibility of part areas of the lead frame is ensured, pressing a thermosetting compression molding compound into the mold while enclosing the populated lead frame, coating the underside of the thus populated lead frame by thermal spraying in at least the electrically conducting areas and overlapping also the predominant areas of the spaces, filled with mold compound.

  • Patent number: 8118211
    Abstract: A method for the low-temperature pressure sintering of at least one electronic unit to be contacted thermally, firmly connected mechanically, and located on a substrate, comprising the following steps: pressing the electronic unit using a mold enveloping matrix while sparing a connecting surface of the substrate for a heat sink connection, providing a heat sink plate, applying a sintering connecting layer onto the spared region of the connecting surface and/or onto to the region of the heat sink plate provided for contacting, and bonding of the heat sink plate to the substrate of the electronic unit in the region of the connecting surface using silver low-temperature pressure sintering technology.
