  • Patent number: 11276680
    Abstract: A temperature protected power semiconductor device has a substrate which includes a power field effect transistor (FET) and a thermosensitive element. The power FET has a gate electrode connected to a gate, a drift region, and first and second terminals for a load current. The load current is controllable during operation by a voltage applied between the gate and the first terminal. The thermosensitive element has a first contact connected to one of the gate electrode and first terminal of the power FET, and a second contact connected to the other one of the gate electrode and first terminal. The thermosensitive element is located close to the power FET and thermally coupled thereto. The thermosensitive element is configured to cause the power FET to reduce the load current in case of an exceedance of a limit temperature of the power FET, by interconnecting the gate and first terminal.

  • Patent number: 9911808
    Abstract: A method for forming a semiconductor device includes incorporating first dopant atoms of a first conductivity type into a semiconductor substrate to form a first doping region of the first conductivity type. Further, the method includes forming an epitaxial semiconductor layer on the semiconductor substrate and incorporating second dopant atoms of a second conductivity type before or after forming the epitaxial semiconductor layer to form a second doping region including the second conductivity type adjacent to the first doping region so that a pn-junction is located between the first doping region and the second doping region. The pn-junction is located in a vertical distance of less than 5 ?m to an interface between the semiconductor substrate and the epitaxial semiconductor layer. Additionally, the method includes thinning the semiconductor substrate based on a self-aligned thinning process. The self-aligned thinning process is self-controlled based on the location of the pn-junction.

  • Patent number: 9768120
    Abstract: A semiconductor device includes a chip carrier and a semiconductor die with a semiconductor portion and a conductive structure. A soldered layer mechanically and electrically connects the chip carrier and the conductive structure at a soldering side of the semiconductor die. At the soldering side an outermost surface portion along an edge of the semiconductor die has a greater distance to the chip carrier than a central surface portion. The conductive structure covers the central surface portion and at least a section of an intermediate surface portion tilted to the central surface portion. Solder material is effectively prevented from coating such semiconductor surfaces that are prone to damages and solder-induced contamination is significantly reduced.
