  • Publication number: 20250107202
    Abstract: A transistor device is disclosed. The transistor device includes a semiconductor body and plurality of transistor cells. Each transistor cell includes: a drift region and a source region of a first doping type; a body region of a second doping type complementary to the first doping type; a field shaping region of the second doping type connected to a source node; and a gate electrode connected to a gate node. The gate electrode is arranged in a trench extending from a first surface into the semiconductor body. The gate electrode is dielectrically insulated from the body region by a gate dielectric. At least portions of the gate electrode are dielectrically insulated from the drift region by a field dielectric. The field shaping region adjoins the trench. The field dielectric comprises a high-k dielectric.

  • Publication number: 20250006814
    Abstract: A method for forming an interface layer on a silicon carbide body comprises removing an oxide layer from a surface of a silicon carbide body to obtain a silicon carbide surface. The silicon carbide body comprises a source region of a first conductivity type and a body region of a second conductivity type. The method further comprises after removing the oxide layer, depositing an interface layer directly on the silicon carbide surface. The interface layer has a thickness of less or equal to 15 nm. The method further comprises forming an electrical insulator over the interface layer, and forming a gate electrode over the electrical insulator.
