  • Patent number: 12406883
    Abstract: A power semiconductor component includes a power semiconductor partial structure having an insulating layer arranged on an upper side of a semiconductor body. A contact hole arranged on an upper side of the insulating layer proceeds from that side, extending at least partly within the insulating layer. An adhesion promoter layer arranged on an upper side of the power semiconductor partial structure at least partly covers the insulating layer upper side and a surface of the contact hole. A tungsten-comprising layer arranged on the adhesion promoter layer at least partly covers the adhesion promoter layer and has a first thickness in a region of the contact hole and dimensioned such that the tungsten-comprising layer fills the contact hole. The tungsten-comprising layer has a second thickness in the region of the insulating layer upper side which is less than the first thickness. A connection layer is arranged on the tungsten-comprising layer.

  • Patent number: 10741541
    Abstract: A method of manufacturing a semiconductor device includes forming an amorphous silicon layer over a first isolation layer. The method further includes simultaneously forming a gate oxide layer of a transistor device and transforming the amorphous silicon layer into a polycrystalline silicon layer by a thermal oxidation process. Herein a cover oxide layer is formed on the polycrystalline silicon layer.

  • Patent number: 9728529
    Abstract: A semiconductor device comprises a semiconductor body having a first surface and a second surface opposite to the first surface. The semiconductor device further includes a first isolation layer on the first surface of the semiconductor body and a first electrostatic discharge protection structure on the first isolation layer. The first electrostatic discharge protection structure has a first terminal and a second terminal. A second isolation layer is provided on the electrostatic discharge protection structure. A gate contact area on the second isolation layer is electrically coupled to the first terminal of the first electrostatic discharge protection structure. An electric contact structure is arranged in an overlap area between the gate contact area and the semiconductor body. The electric contact structure is electrically coupled to the second terminal of the first electrostatic discharge protection structure and electrically isolated from the gate contact area.

  • Publication number: 20170062276
    Abstract: A layer stack is formed on a main surface of a semiconductor layer, wherein the layer stack includes a dielectric capping layer and a metal layer between the capping layer and the semiconductor layer. Second portions of the layer stack are removed to form gaps between remnant first portions. Adjustment structures of a second dielectric material are formed in the gaps. An interlayer of the first or a third dielectric material is formed that covers the adjustment structures and the first portions. Contact trenches are formed that extend through the interlayer and the capping layer to metal structures formed from remnant portions of the metal layer in the first portions, wherein the capping layer is etched selectively against the auxiliary structures.
